Automated penetration testing that shows its work
You've been asked for a pen test by a customer, an insurer or a security questionnaire, and the quotes are full of day rates and scoping calls. BreachLine gives you an AI security engineer, Nebula, on a monthly plan with the price on the page. It tests the systems you're authorised to test, proves flaws safely where they can be exploited and checks your fixes when you're done.
Why testing once a year leaves gaps
A one-off penetration test is a snapshot. Your app, your APIs and your cloud keep changing after the report lands, and booking the next test means another quote and another wait. Small teams end up testing less often than they'd like, or relying on scanner output that still needs someone to work out what's real.
How does automated penetration testing work?
- 01
Tell it what to test.
Set the targets you're authorised to test, the scope, any exclusions and test accounts. You can brief it in the workspace.
- 02
It plans and runs the work.
Nebula plans steps and uses browser, terminal and security tools, adjusting as results come in.
- 03
You review real evidence.
Where a flaw can be exploited, Nebula proves it safely, with reproduction steps and a suggested fix.
- 04
Fix and retest.
Ask Nebula to verify your fix, and it retests the original issue on the changed system.
Updates come to you by email.

How much does automated penetration testing cost?
Nebula vs a one-off manual pen test
AI pentest vs CREST pentest: which do you need? Some customers, contracts or frameworks ask for a test run by people. If that's you, our penetration testing services are scoped and quoted separately. See services
Frequently asked questions
Is automated penetration testing the same as a vulnerability scan?
No. A scanner runs a set list of checks. Nebula plans a sequence of tests, uses several tools and investigates the results, and, where a flaw can be exploited, proves it safely.
How much does automated penetration testing cost with BreachLine?
Plans start at £399 a month. Testing and retests both use credits (retests aren't free), and you can top up at any time.
Will this satisfy a customer or insurer asking for a pen test?
It depends on what they ask for. Some accept evidence of regular testing; others require a test run by people or a particular standard. Check the wording, and talk to us if you need a scoped services engagement.
Can Nebula retest my fixes?
Yes. Ask it to verify a fix and it retests the original finding on the changed system. Retests aren't free: they use credits from your plan, like other testing.
What do I need to get started?
Systems you're authorised to test, a clear scope and any test accounts Nebula should use. Book a demo and we'll help you pick a plan.
Is BreachLine Cyber Essentials certified?
Yes. BreachLine is Cyber Essentials certified by CDS Defence & Security, valid to August 2027.
