Penetration Testing in Manchester: Find the Way In Before Someone Else Does.
Penetration testing in Manchester for businesses that need to know what an attacker could actually reach: internet-facing systems, Microsoft 365, staff devices, web applications and Wi-Fi. We scope every pen test with you, test under written authorisation, and hand over a plain-English report with an optional retest to prove the fixes worked.
What a Manchester penetration test actually involves, in plain terms
Penetration testing in Manchester is an authorised, controlled attempt to break into your systems, including your external network, internal network, Microsoft 365 and cloud, web applications and wireless, using the techniques a real attacker would use. You receive a prioritised report showing what was exploitable, the evidence, and how to fix it. Unlike a vulnerability scan, a pen test proves what can really be reached and what an attacker could do once inside.
The idea is simple even if the work is not. Somebody with an attacker’s skills and your written permission tries to do what a criminal would do: find a door, get through it, and see how far they can travel. The NCSC describes penetration testing as a way of gaining assurance in the security of a system by attempting to breach it using the tools and techniques an adversary might use, and its guidance on commissioning a test is worth reading before you buy one from anybody, including us.
What makes a test valuable is the gap between “this system has a vulnerability” and “this vulnerability let us read the finance team’s files.” A scanner reports the first. A tester demonstrates the second, and that difference is what lets a managing director or finance director decide what to fix this month and what can wait. It is also what turns a security budget conversation from fear into prioritisation. Our wider penetration testing programme covers the UK; this page is about how it works for Manchester organisations specifically.
Pen test, vulnerability scan or red team: pick the one that answers your question
Much of the confusion in this market comes from vendors using the same words for very different activities. Before asking for quotes, decide which question you are really trying to answer, because the answer decides the type of test and, to a large extent, the cost.
| Approach | The question it answers | Best used for | Limitation |
|---|---|---|---|
| Vulnerability scan | Which known weaknesses exist on these systems? | Routine hygiene, monthly or quarterly | Does not prove exploitability or show how issues chain together |
| Penetration test | What can an attacker actually do with these weaknesses? | Annual assurance and after significant change | Scoped to defined systems and a fixed period of effort |
| Red team exercise | Can we detect and stop a determined attacker pursuing a goal? | Organisations with an established security function | Costly and unnecessary for most small and mid-sized firms |
| Cyber Essentials Plus verification | Are the five basic controls in place on sampled devices? | Certification demanded by customers or tenders | A technical check against a standard, not a full attack simulation |
For most Manchester SMEs the sensible pattern is a combination: continuous vulnerability management through managed security and managed EDR, an annual penetration test to check the whole picture, and Cyber Essentials when customers ask for it. Buying a pen test to cover a gap that a basic control would close more cheaply is a common and expensive mistake, and we would rather tell you that than sell you the test.
Five places attackers look first, and how each one gets tested
Every environment differs, but attackers follow well-worn paths. Our scoping conversation starts from these five because they account for most of the real-world routes into small and mid-sized organisations. Which of them go into your test depends on what you run, what you hold and what a breach would cost.
1. Internet-facing systems
Firewalls, VPN gateways, remote desktop, mail servers and websites are the doors visible from outside. External testing looks for exposed management interfaces, outdated software, weak or reused credentials on remote access and misconfigurations that let someone in without a single stolen password. Remote access appliances are a regular target precisely because they sit on the edge and are easy to forget to patch, so we also review how your managed firewall or firewall configuration is set up and maintained.
2. Microsoft 365 and Entra ID identity
For most businesses, the identity layer is the real perimeter. We check whether multi-factor authentication covers every account that matters, whether legacy authentication is still switched on, how conditional access is configured, who holds administrator roles and whether any have more privilege than their job needs. We also look for risky application consents and mailbox forwarding rules, which attackers use to stay hidden after a successful phish. The same team that handles Microsoft 365 support and Azure reads the findings, so remediation advice is practical rather than generic.
3. Internal network and staff devices
Assume a member of staff has clicked something they should not have. Internal testing starts from that position and asks how far an attacker could get: whether they can escalate privileges, move sideways between machines, reach file servers or the finance system, and whether anything would notice. Flat networks, shared local administrator passwords and unpatched software are the usual contributors, and the result is a clear picture of how much damage one compromised laptop could do.
4. Web applications and APIs
If you run a customer portal, an online shop or an internal line-of-business web application, it deserves its own test. We assess authentication and session handling, access control between users, input handling and API exposure, working to categories such as those in the OWASP Top 10. Application testing is best done before launch and after significant releases, when fixing a flaw is cheapest.
5. Wi-Fi and shared-building exposure
Many city-centre firms occupy shared or serviced offices, which makes wireless design matter more than people expect. We test whether guest and corporate networks are properly separated, whether pre-shared keys are weak or widely known, and whether rogue access points could trick staff devices into connecting. On-site wireless and internal testing is where having engineers based locally makes a practical difference.
Where a Manchester test should focus, sector by sector
Greater Manchester’s economy is unusually varied, from the legal and financial firms around Spinningfields and Deansgate, to creative and digital businesses in the Northern Quarter, Ancoats and MediaCityUK, to the health and education organisations along the Oxford Road corridor and the manufacturers and distributors across Trafford Park and the surrounding industrial areas. The exposures differ, so the priorities for a first test should too.
| Sector | Where exposure tends to sit | What we would put in scope first |
|---|---|---|
| Legal and professional services | Confidential client data, payment-diversion fraud, document management and remote access | Microsoft 365 identity, email security, file sharing permissions and remote access; see law firm IT and accountancy IT |
| Financial services and insurance | Regulated data, third-party integrations and attractive targets for criminals | External perimeter, APIs and third-party access paths; see cybersecurity for financial services |
| Digital, creative and technology | SaaS sprawl, client assets, source code and heavy remote working | Cloud configuration, single sign-on, web applications and device management |
| Health, life sciences and education | Sensitive personal data, older systems and large numbers of users | Internal network segmentation, privileged access and device patching; see healthcare IT |
| Manufacturing and logistics | Flat networks, ERP systems and remote access for suppliers and engineers | Internal network, supplier access and ERP exposure; see manufacturing IT |
| Retail and e-commerce | Card data, web storefronts and third-party plug-ins | Web application and payment-environment testing, with PCI DSS in mind |
One boundary worth stating plainly: operational technology and industrial control systems need specific scoping and safety rules before anything is touched. If part of your estate should be excluded or tested only under special conditions, we will say so at the scoping stage rather than discover it mid-test.
What auditors, insurers and customers will accept as evidence of testing
Many Manchester firms come to us because somebody else asked: a customer’s procurement team, an insurer at renewal, an auditor during an ISO 27001 review. Knowing exactly what is being requested saves money, because a pen test is the right answer to some of these questions and the wrong one to others.
| Requirement | What it asks of testing | Where a pen test fits |
|---|---|---|
| Cyber Essentials Plus | Independent technical verification of five basic controls on sampled devices | Not a pen test; a pen test gives broader assurance but does not replace the certification |
| ISO 27001 | Technical vulnerability management and security testing as part of your management system | A common way to evidence that testing is planned, performed and acted on |
| PCI DSS | Penetration testing of in-scope environments at least every 12 months and after significant change | Directly required for organisations handling card data in scope |
| UK GDPR | A process for regularly testing and evaluating the effectiveness of security measures | Supports your Article 32 position; useful evidence if the ICO ever asks |
| Cyber insurance | Evidence of controls such as MFA, backups and patching; some insurers ask for recent test results | Strengthens a proposal and shows controls work in practice, not just on paper |
| Public sector and CNI | Testing by firms assured under the NCSC CHECK scheme | Check early whether your contract requires CHECK before you commission anyone |
If you hold the insurance side of this in your head as a vague worry, our industry whitepapers include plain-English papers on why cyber policies sometimes fail to pay out and on incident response. For a wider review of controls that goes beyond a technical test, our security audit work looks at policy, process and people alongside the technology.
From first call to retest: how we run a penetration test
A scoping conversation, not a sales call
We ask what you run, what you hold, what worries you and what has changed recently. The output is a written scope: which systems, which test types, which dates and which approaches are off limits.
Written authorisation and emergency contacts
Nothing is tested without signed permission from someone entitled to give it, covering any third-party hosts involved. We agree who to call, at what hour, if something unexpected happens during testing.
Reconnaissance and testing
Testers map what is visible, look for ways in, and attempt to exploit what they find within the agreed rules. Destructive techniques are avoided unless specifically agreed, and anything that could affect live service is discussed first.
Immediate notice of anything critical
If a serious, easily exploited weakness turns up, you hear about it straight away rather than in the final report, so you can act while testing continues.
Reporting and a debrief call
You receive a written report and a walkthrough with the people who did the testing, so both your technical team and your leadership understand what was found and why it matters.
Fixing and, if you want it, retesting
Your IT team, or ours, works through the findings in priority order. A focused retest then confirms that the fixes worked, which is the evidence auditors and insurers like most.
What lands on your desk afterwards, and what a good report should contain
The report is the product. A technically brilliant test delivered as a 90-page scan export is close to worthless, because the people who need to act on it will not read it. A useful report is written for two audiences at once: the technician who has to fix things and the director who has to fund the fixing.
- An executive summary in plain English, with an overall view of risk
- Findings ranked by severity and by how easily they can be exploited
- Evidence for each finding, including steps to reproduce it
- Business impact explained without jargon
- Specific remediation guidance your IT team can follow
- Notes on what was not tested, so nobody assumes coverage they do not have
What moves the price of a pen test in Manchester, and how we quote it
Anyone who quotes a fixed price for “a penetration test” without asking what is being tested is guessing. Cost follows effort, and effort follows scope. We would rather agree the scope first and give you a fixed figure you can approve, with no day rate quietly growing in the background.
- Number of external IP addresses and services in scope
- Size and complexity of the internal network and number of sites
- Number of Microsoft 365 tenants, users and privileged roles
- Size and complexity of any web application or API
- Whether on-site wireless and internal testing is needed
- Depth of testing and how much manual effort it demands
- Whether a formal retest is included
- Reporting requirements for auditors, insurers or customers
| Arrangement | Best suited to | How it works |
|---|---|---|
| One-off test | A first test, a customer request or a pre-renewal check | Fixed scope and fee, report and debrief, with an optional retest |
| Annual programme | Firms that need regular assurance for ISO 27001, PCI DSS or insurers | A yearly test with the scope reviewed as your environment changes |
| Test and fix | Teams without spare capacity to remediate | We test, then help close the findings and retest to confirm |
| Pre-launch application test | New portals, apps and APIs before go-live | Focused testing timed to your release plan, before customers see it |
Smaller organisations are not priced out. A proportionate scope, often starting with the external perimeter and Microsoft 365 identity, can give a small business much of the value at a fraction of the effort of a full estate test. Our cybersecurity for small businesses work follows the same principle: cover the biggest risks first and widen the scope as budgets allow.
Questions to put to any penetration testing company in Manchester, including us
Pen testing is a market where it is hard to judge quality from a brochure. These questions separate careful providers from the rest, and a good provider will welcome them. Some customers and public-sector schemes require particular accreditations such as CREST membership or CHECK status, so find out what applies to you before you start collecting quotes.
| Ask | A good answer sounds like | A warning sign |
|---|---|---|
| Who will actually test us, and what qualifications do they hold? | Named testers with recognised practical certifications and relevant experience | Vague references to “our team” or a scanner run by a salesperson |
| What is in scope and what is not? | A written scope, exclusions and rules of engagement before any work starts | A fixed price quoted before anyone has asked about your systems |
| How will you avoid disrupting live systems? | Agreed testing windows, avoidance of destructive techniques, a named contact | “It never causes problems”, with no detail |
| Can we see a sample report? | A redacted example with evidence, ranking and remediation steps | Reluctance to show anything, or a scan export presented as a report |
| Is retesting included or priced separately? | A clear answer, ideally a focused retest after fixes | No mention of retesting at all |
| Do you also manage our IT, and how is that handled? | A transparent explanation of how findings about the provider’s own work are reported | Defensiveness, or findings that conveniently never touch the provider’s work |
| Where is our evidence stored, and when is it deleted? | Defined storage, access and deletion arrangements agreed in writing | No answer, or evidence kept indefinitely on shared systems |
On the independence question, we manage IT for many clients and also test security, so we will tell you in writing how any finding that points at configuration we look after is reported to you, and you are free to use separate testers if you prefer that separation.
A Manchester team you can actually sit down with
Our head office is at NorthStar, 135–141 Oldham Street, in the Northern Quarter, and Manchester has been home since 2006. Scoping workshops can happen in person or on a video call, and internal network and wireless testing is done on site across Greater Manchester, while external and cloud testing can run remotely without affecting how you work.
We are Cyber Essentials Plus certified ourselves and hold Microsoft Solutions Partner status including the Security designation, so we are tested against the same standards we recommend. If you are weighing us against a national firm, the practical difference is who you can phone. See how our IT support in Manchester works day to day, or read about our wider cyber security company in Manchester offering.
After the test: closing the gaps and keeping them closed
A test captures a moment. Configurations drift, staff change and new software arrives, so the value of a pen test depends on what happens next. Most findings fall into a handful of buckets: identity controls that need tightening, patches that were missed, network segmentation that was never built, and monitoring that would not have noticed the intrusion the testers carried out.
That is where ongoing protection matters. Managed EDR watches endpoints around the clock, our managed security arrangements handle patching and monitoring, and day-to-day managed IT support keeps configuration tidy between tests. Retesting a year later then shows whether the improvements held, which is a far stronger story for an insurer or customer than a single report sitting in a drawer.
How a first test might unfold for a 60-person Manchester professional firm
This is a representative scenario rather than a named client, included to show how scoping, testing and follow-up fit together.
A key client asks the firm for evidence of independent security testing before renewing a contract. The firm has never been tested and is unsure what a sensible scope looks like.
Scoping settles on the external perimeter, Microsoft 365 identity and an internal assessment from a standard staff laptop. Testers find an old remote access gateway still exposed, administrator accounts without multi-factor authentication and file shares open to far more staff than necessary.
The firm closes the critical findings within the agreed window, a retest confirms the fixes, and the report and retest letter go to the client alongside the firm’s Cyber Essentials certificate. The conversation shifts from “are you secure?” to “here is the evidence.”

How much does penetration testing cost in Manchester?
It depends on scope: the number of external systems, size of the internal network, Microsoft 365 users and privileged roles, any web applications and whether on-site wireless testing is needed. We agree scope first, then give a fixed quote, so you know the cost before work begins.
How long does a penetration test take, and will it disrupt us?
Duration follows scope, from a few days of effort for a focused external and Microsoft 365 test to longer for larger estates. Testing is planned with agreed windows and rules of engagement, and destructive techniques are avoided unless you specifically agree them.
Does Cyber Essentials Plus include a penetration test?
No. Cyber Essentials Plus involves independent technical verification of the five basic controls on sampled devices. It is valuable, but narrower than a penetration test, and the two answer different questions.
How often should a Manchester business carry out a pen test?
Annually is the common benchmark, plus after significant changes such as a cloud migration, a new application or an office move. Where PCI DSS applies, testing is required at least every 12 months and after significant change.
Do you test internal networks and Wi-Fi on site?
Yes. Internal and wireless testing is done on site across Greater Manchester, while external and cloud testing can be run remotely. We confirm the approach during scoping.
Can you test Microsoft 365 and Azure?
Yes. Cloud testing reviews identity, multi-factor authentication, conditional access, privileged roles, application consents and configuration weaknesses that attackers commonly use.
Can you test our web application or API before launch?
Yes. We assess authentication, access control, input handling and API exposure, ideally before go-live and after major releases, when fixes are quickest and cheapest.
What do you need from us before testing starts?
A clear idea of your priorities, signed authorisation for the agreed scope, details of any third-party hosts involved, named contacts and reachable emergency numbers, and any test accounts needed. We take you through the list during scoping.
Will testing crash our systems?
Risk is managed through scoping, agreed testing windows and avoiding destructive techniques, but no responsible tester can promise zero risk. That is why we agree what to do, and who to call, if something behaves unexpectedly.
What happens if you find something critical during testing?
You are told promptly rather than waiting for the final report, so you can start fixing the most serious issues while testing continues.
Do you offer retesting after we have fixed the findings?
Yes, and we recommend it. A focused retest confirms that fixes worked and gives auditors, insurers and customers evidence that the issues were resolved, not just noted.
Is penetration testing worth it for a small business?
Yes, if it is scoped proportionately. Starting with the external perimeter and Microsoft 365 identity covers the most common routes in without the cost of a full estate test, and the scope can grow as budget allows.
Can the company that manages our IT also test it?
It can, provided independence is handled openly. Ask how findings about the provider’s own work are reported. We confirm our approach in writing, and you are always free to use separate testers if you prefer.

The best penetration testing in Manchester is not the one that finds the most vulnerabilities; it is the one that tells you which few matter, proves it, and leaves your team able to fix them. That means a scope agreed in advance, testers you can name, a report written for both technicians and directors, and a retest that closes the loop. Whether the trigger is a customer questionnaire, a renewal, an audit or simply a wish to know where you stand, the right next step is a short conversation about what you run and what a breach would cost you.
