Your last pentest is already out of date
You ship weekly, but you test once a year. Everything released since that report is untested and unproven.
PenetrationTesting,AdversarySimulation&ContinuousSecurityTesting
CREST-aligned penetration testing, adversary simulation and AI-assisted continuous testing for organisations that need more than an annual penetration test.

CREST Approved
Independently assessed against the highest technical and operational standards in the penetration testing industry.
Accreditation
CREST approved penetration testing
CREST accreditation means our people, processes and reporting have been independently validated — so you can trust the results and prove them to anyone who asks.
CREST-approved methodology
Every engagement follows CREST-aligned scoping, testing and reporting standards — repeatable, auditable and accepted by regulators, insurers and enterprise procurement teams.
Qualified, vetted consultants
Testing is delivered by certified consultants working to CREST codes of conduct and ethics, with background-checked personnel and strict handling of client data.
Evidence your stakeholders accept
CREST-aligned reports and attestation letters map findings to risk, so boards, auditors and customers get assurance in a format they already recognise.
Sound familiar?
Security testing that ends when the report lands
Most teams don't have a testing problem — they have a visibility, validation and follow-through problem.
You can't see your whole attack surface
Forgotten subdomains, shadow cloud assets and exposed services appear faster than anyone can inventory them.
Findings sit in a PDF, not a fix
A 90-page report lands in an inbox. Nobody owns the remediation and nothing gets validated as fixed.
Compliance deadlines arrive too fast
Customers, auditors and insurers want evidence now — and procurement stalls until you can produce it.
The Pentesys way
From one-off testing to a programme that never stops
One platform, one team, one continuous loop — discover, validate, remediate, prove.
STEP 1
Know what's exposed — continuously
Mirage Surface maps every internet-facing asset and keeps watching, so new exposure is found before an attacker finds it.
Continuous discovery, not a point-in-time snapshot
STEP 2
Prove what's actually exploitable
AI-assisted testing runs constantly to speed up coverage, and every finding is validated by a human tester so your team only chases real risk.
Faster testing without the noise
STEP 3
Fix it, retest it, evidence it
Findings flow into your existing tooling with owners and SLAs, and free retesting closes the loop with audit-ready evidence.
CREST-aligned reports and attestation letters
Which sounds like you?
Start from your problem, not our service list
Tell us what you're trying to achieve and we'll shape the right programme around it.
“A customer won't sign until we show a pentest report.”
We scope quickly, test to CREST-aligned standards and hand you a report plus an attestation letter your buyer's security team will accept.
Deal unblocked in weeks, not quarters
“We ship every week and testing can't keep up.”
Continuous AI-assisted testing runs against every release and our consultants validate anything that matters, so coverage moves at your pace.
Always-on assurance between releases
“We don't actually know what we have exposed.”
We map your external estate, surface shadow assets and forgotten subdomains, then keep monitoring as your footprint changes.
A live picture of your attack surface
“The board wants proof we're getting safer.”
Risk trends, remediation SLAs and free retesting give you evidence of progress rather than a snapshot of problems.
Board-ready reporting every month
How we help
