Penetration testing for Windsor businesses

Find the Weak Points Attackers Would Use

A penetration test is an authorised, simulated attack on your own systems. A tester tries to get in through your internet connection, firewall, website, Wi-Fi and staff accounts, using the methods criminals use, and records every route that works. Unlike a scan on its own, a pen test proves which flaws can be exploited.

It suits Windsor firms that hold client data, take bookings online, run guest Wi-Fi or are working towards Cyber Essentials Plus, and anyone whose insurer or client has asked for proof of testing.

What an untested weakness can lead to

  • An open remote access service that lets an outsider reach your file server
  • A website form that leaks customer records to anyone who knows where to look
  • A guest Wi-Fi network that gives visitors a path to the PCs and servers in your office
  • An insurer or client asking for test evidence you cannot produce when a renewal is due

Our difference

Why Windsor Firms Choose Us for Pen Testing?

A scan tells you what might be wrong. A pen test shows what an attacker could really do with it, and our report tells you what to fix first, in plain English.

  • Testing from outside

    We test everything that faces the internet: your firewall, VPN, remote access, email server, website host and public IP addresses, looking for ways in from outside.

  • Internal and Wi-Fi tests

    We connect on site, test your office and guest Wi-Fi, and see how far an intruder could move from a single PC.

  • Website and web app tests

    We check your website, booking forms and customer logins for flaws such as weak passwords and data leaks.

  • Clear, plain-English report

    Every finding is rated by severity, with evidence and a fix. Directors get a short summary, and your IT team gets the detail.

  • Retest after fixes

    Once the fixes are in, we test again to confirm each finding is closed, so you have proof for clients.

Our process

A Clear Pen Testing Process From Scope to Retest

Every penetration test starts with a written scope, so you know what we will test, when and how. We agree test windows that avoid your busy periods, keep you updated while the work runs and stop at once if anything risks disrupting your systems.

  1. Scope: agree the targets and rules

    We list the IP addresses, websites, offices and accounts in scope, agree dates and rules of engagement, and confirm everything in writing first.

  2. Test: run the attacks

    Our testers combine vulnerability scanning with manual testing, trying each weakness to see how far it could take a real attacker.

  3. Report: rank findings by risk

    You get a written report with every finding rated by severity, the evidence behind it and the steps to fix it, and we talk your directors and IT team through it on a call.

  4. Retest, then test again yearly

    Once fixes are in, we retest to confirm they hold. We suggest testing once a year and after any major change to your IT.

Frequently asked questions

Pen Testing Questions From Windsor Businesses

How much does a penetration test cost in Windsor?

The price depends on the scope: how many IP addresses, websites, offices and user accounts we test, and whether the work is external only or includes an internal test on site. We agree the scope with you first and give you a fixed quote in writing, so the cost does not change once testing starts.

Is a vulnerability scan good enough?

A vulnerability scan is automated and lists known weaknesses, including some false alarms. A pen test adds a person who confirms which ones are real, links them together and shows what an attacker could reach. Scans suit regular checks, and a pen test goes deeper.

Will testing disrupt our staff or systems?

Testing is planned to avoid disruption. We agree test windows, avoid risky techniques on live systems unless you approve them, and stop straight away if a service is affected. Most staff will not notice the work.

Does this cover Cyber Essentials?

No. Cyber Essentials Plus has its own audit by a certified assessor. A pen test goes further, and fixing its findings helps you pass.

What happens if you find a serious flaw?

We tell you straight away rather than waiting for the report. If a weakness puts your data at immediate risk, we explain the quick fix and can apply it for you, then carry on testing the rest of the agreed scope. Call 01753 255436 to talk it through.

How often should we have a penetration test?

At least once a year, and again after a big change such as a new firewall, a new website, an office move or a cloud migration. Some clients and insurers set their own timetable, so check your contracts and policy wording too.

Do you test businesses outside central Windsor?

Yes. We test firms in Eton, Datchet, Slough, Maidenhead, Ascot, Egham and Staines. External tests run remotely, and internal tests take place on site.
