BreakMesh – Vulnerability Simulator & Cyber Range

Website security testing

We test your website the way an attacker would.

Then we tell you exactly what to fix. BreakMesh looks for the weaknesses an attacker would look for, without changing or deleting anything. You get a clear list of what is exposed, how serious each item is, and the steps to resolve it. Your first scan is free and takes about two minutes.

In plain English

What actually happens when you run a scan

No security background needed. Three steps, about two minutes.

You tell us your web address

You prove the site is yours by adding one line of text to your domain settings. We show you exactly what to paste and where. This stops anyone pointing us at a site they do not own.

We look for weak spots

We look for the same weaknesses an attacker would: outdated software, settings left open, and routes to data that should be private. We read and test only — nothing is deleted, altered or overloaded.

You get a list of what to fix

Each item states what we found, why it matters and what to change, ordered by urgency. Pass the list to whoever maintains your site, or send the report to a customer or auditor who has asked about your security.

For example, a real finding looks like this

Medium

Your site tells visitors which server software it runs

What this means: every page reveals the exact version of the software running your site. Attackers collect this to identify versions with known weaknesses, which removes the guesswork for them.

What to do: disable the version banner in your web server settings. It is a one-line change, and we show you the line.

Why teams use BreakMesh

Whether you build it, run it, or answer for it

One place to check your website, your logins, the services your app talks to, your cloud accounts and your mobile app. Start free with the basics, then add more as you need it.

For founders & CTOs

Know where you stand at a glance

See how safe your site is right now, what to deal with first, and whether things are getting better each month.

For developers & security teams

Know what needs fixing — and why

Every issue comes with the page it affects, proof that it is real, how serious it is, and the change to make.

For agencies

Turn security work into client-ready evidence

Set checks to run on their own, put your own logo on the reports, and show clients what you found and fixed.

How it works

Four steps, start to finish

The same four steps every time, so you can compare this month with last month.

1

Add your target

Enter the web address of a site or app you own or run.

2

Prove it is yours

Paste one line of text into your domain settings. We show you exactly what and where. This stops anyone scanning a site they do not own.

3

Pick what to check

Start with the free basics, or add checks for your logins, your app's services and more.

4

Fix and share

Work down the list, watch your score improve, and send a report to anyone who needs one.

You always prove you own a site before we scan it. Checks that need a login, or a file you upload, ask for your permission separately.

Two levels

Identify the weaknesses, or prove them

Most teams start with the first and add the second later. They serve different purposes; one is not a replacement for the other.

Standard BreakMesh checks

Find the weak points

  • Never alters or slows anything
  • Safe to run repeatedly, on a schedule
  • Suited to routine review, or a check before a release
  • Every issue rated, proven and explained

Coverage

What we can check

Start free with the basics. Add the rest when you need it — you only pay for what you turn on.

Logins and app connections

Can someone guess their way in, stay signed in as another person, or reach data belonging to a different account?

Your defences from outside

Do you block bots and floods of traffic? Is your real server hidden? Are there forgotten sub-sites still online?

Explore Threat Readiness →

Your cloud account

Is any storage or setting left open to the public by mistake? We only read — we never change anything. Works with Amazon, Microsoft and Google.

Explore Cloud Security →

Your mobile app

Upload your Android or iPhone app file and we look inside it for passwords left in the code and data stored unsafely. Nothing is sent over the network.

Trust & safety

We only test what you have authorised

You prove a site is yours before we test it, we stay within what you approved, and we keep a record of everything we did. Anything more intrusive requires your written approval first.

See our safety model

You prove ownership first

We will not scan a website until you have demonstrated you control it.

We stay within what you approve

We only reach the sites and pages you have approved. Nothing else.

Nothing is changed

Standard checks never delete data, alter settings, or overload your site with traffic.

You approve first

Checks that sign in, or that test more deeply, run only when you enable them.

Deeper testing requires a signature

Before it runs, you sign a short agreement setting out what may be tested, and for how long.

Every finding is evidenced

Each item includes proof it is real, how serious it is, and what to change.

Audit-ready evidence

Paperwork for security reviews, built as you go

When a big customer or an auditor asks how you handle security, they usually ask against a standard called SOC 2. We sort your results into the categories they ask about, so you are not assembling it by hand the week before.

FAQ

Common questions

Starting with the ones people ask before they have used anything like this.

What is BreakMesh, in one sentence?

We check your website the way someone trying to break in would look at it, without breaking anything, and then hand you a plain list of what is weak and how to fix it.

I am not technical. Is this for me?

Yes. Every issue is written in ordinary language: what we found, why it matters, and what to change. If someone else built your site, you can forward the list to them — it tells them exactly what to do. You do not need to understand security to know where you stand.

Will this break or slow down my site?

No. Normal checks only look and test gently — they never delete data, change your settings, or send enough traffic to slow anything down. The more forceful tests are a separate product, switched off unless you sign an agreement turning them on.

Why do I have to prove I own the site?

So nobody can point us at a website they have nothing to do with. You paste one line of text into your domain settings — we show you exactly what and where — and that is it. Checks that use a login, or a file you upload, ask for your permission a different way instead.

Does this replace hiring a security firm?

Not entirely. We cover a lot, automatically and repeatedly, for a fraction of the cost. But if a customer or a regulation specifically requires a human expert to test your systems by hand, you will still need that. Many teams use us continuously and bring in people once a year.

Is a person doing the testing?

No — it is all software, including the more forceful tests. That is why it is fast and repeatable, and why you set the boundaries in writing beforehand rather than briefing someone.

What do I actually get at the end?

A list of what passed and what needs attention, sorted by how urgent it is, with proof and fix steps for each item, plus how you compare with last time. You can download it as a PDF to send to someone, and agencies can put their own logo on it.
