Penetration testing in Petersfield, Hampshire
We try to break in the way a real attacker would, then show you in plain English what we got into and how to close it. Network, Wi-Fi, Microsoft 365, cloud and web application pen tests for businesses across East Hampshire.
The basics
Penetration testing, also called pen testing or ethical hacking, is an authorised, simulated cyber attack on your systems. A tester uses the same techniques as a real attacker to find weaknesses in your network, cloud accounts and websites, proves which can actually be exploited, and shows you how to fix them.
It isn't the same as a vulnerability scan. A scan is automated software that lists possible problems. A penetration test puts a person in charge: they confirm which problems are real, chain small issues together the way attackers do, and rank what matters for your business.
The aim is practical assurance: a clear fix list before a criminal, insurer, supplier or auditor forces the issue.

Penetration testing & vulnerability scanning
Find out where your network, cloud and applications are really exposed, then get a clear, ranked plan from our in-house cyber team to fix it. Ask us for a pen test quote and you'll get a straight price up front.
Free, one-time
A quick check of everything you have facing the internet, looking for the gaps an attacker would spot first.
Ongoing, part of a paid plan
Regular testing by our own cyber specialists, so your security keeps up as your business changes.
Common weaknesses
None of these are exotic. They're common because they're easy to miss, and just as easy for attackers to find.
Open servers, admin pages and services that shouldn't be public.
Passwords that are easy to guess or never changed.
Security settings that don't follow best practice.
Issues in Microsoft 365, Azure or other cloud platforms.
Vulnerabilities in your website or web applications.
The benefits
Attackers go after weak spots, not big names. A penetration test shows you exactly where you're exposed and what to fix first, so you can cut risk early, keep the business running and show customers you take security seriously.
When the test is done you get two things: a short executive summary for decision makers, and a full report listing every finding, the risk it carries and what to do about it.
Find the gaps before criminals do and close them early, so there's less for anyone to exploit.
Independent test results give customers, partners and auditors something solid to point to.
Spot the weaknesses behind ransomware, outages and breaches, then fix them in order of risk.
Thorough testing with a focused scope, clear reports and fixes you can actually carry out, without an enterprise price tag.
How it works
Testing your own systems shouldn't feel risky. Everything is agreed up front, in writing: what we test, when, what's off-limits and who we call if something looks wrong.
Agree what's included and the level of testing.
Identify key systems, users and entry points.
Test for real, exploitable vulnerabilities.
Carry out testing without disrupting your business.
You get a clear report, then we check the fixes worked.
Your report
The report is the part you keep, so we write it for two readers: whoever signs off the budget, and whoever does the fixing. We go through the findings with you on a call.

Frequently asked questions
An authorised, simulated cyber attack on your systems. A tester uses the same techniques a real attacker would to find weaknesses, proves which ones can actually be exploited, and shows you how to fix them.
A scan is automated software that lists possible problems. A penetration test puts a person in charge, who confirms which problems are real, chains small issues together the way attackers do and ranks what matters for your business.
An external test looks at what anyone on the internet can reach, like your website, email and remote access. An internal test shows what someone could do once inside your network, for example from a stolen laptop. Most businesses start with external and add internal later. We'll recommend what fits when we scope the test.
External, cloud and web application testing runs remotely. Internal network and Wi-Fi testing may need us on site, and we can visit businesses around Petersfield.
It shouldn't. We agree in writing what we test, when and what's off-limits, and we avoid anything likely to take systems down. If something looks wrong during the test, we stop and call the contact you've named.
It depends on what's being tested and how big it is. Once we've agreed the scope, you get a fixed quote up front, with no surprises later.
That depends on the scope too. A small external test can be done in a few days, while larger internal or application tests take longer. We'll give you a timeline before we start.
Cyber Essentials checks that the basic controls are in place. A penetration test goes further and shows whether an attacker could actually get past them. Many businesses use both: Cyber Essentials as the baseline, and a pen test for real-world assurance.
Yes. We look at how your Microsoft 365 tenant is set up, including sign-in security, admin accounts, sharing settings and email protection, and show you where it could be tightened.
Yes. We review your cloud setup for exposed services, weak access controls and risky configuration, then give you clear steps to fix what we find.
Usually the live system, because that's what attackers see. We test it carefully within the agreed limits. If a system is fragile or business-critical, testing a copy is an option and we'll talk it through with you.
At least once a year, and again after big changes such as a new website, a new system or a move to the cloud. Some insurers and customers ask for a test every year.
We go through the findings with you on a call so you know what to fix first. Once the fixes are in, we retest to check they worked.
A short executive summary for whoever signs off the budget, plus a full technical section for whoever does the fixing. Every finding comes with its risk level, evidence and the steps to fix it.
