SENIOR-LED PENETRATION TESTING
Find the breachbefore it finds you.
Hands-on testing for your web apps, APIs, cloud and network. Get the report your auditors, customers and board keep asking for, with a clear fix for every risk we find.
Real commitments, not vanity metrics. The bar we hold every engagement to.
FRAMEWORKS & COMPLIANCE
Tested to the standards. Mapped to your compliance.
We don't improvise. Every engagement runs against recognised security methodologies, and each finding maps to the audit evidence you need to show.

WHAT WE TEST
Six ways attackers get in. We cover all of them.
INDUSTRIES WE SERVE
Security shaped to your sector.
Every industry has its own attack surface, data sensitivity and compliance load. Pick yours to see exactly where we focus and what you walk away able to prove.
Fintech & Payments
Money movement is the target. We test the way fraudsters actually operate.
- Stop account takeover before it ships. IDOR, transaction tampering and session flaws.
- Break the business logic limit bypasses, double-spends and race conditions.
- Protect funds & customer PII to hold user trust and banking-partner approval.
PCI DSS
SOC 2Healthcare & HealthTech
Patient data and uptime are non-negotiable. We find the exposure first.
- Prevent PHI exposure across portals, patient APIs and integrations.
- Lock down access control so no account can reach another patient’s records.
- Cut breach & fine risk that erodes patient trust and payer contracts.
HIPAA
HITRUSTSaaS & Technology
Your product is your attack surface, and multi-tenant flaws don’t stay contained.
- Verify tenant isolation so one customer can’t read or touch another’s data.
- Fix broken access control BOLA and BFLA, the top modern API risks.
- Clear enterprise security reviews with the evidence your biggest buyers demand.
SOC 2
ISO 27001E-commerce & Retail
Checkout, coupons and carts get abused at scale. We test them the way bots do.
- Close checkout logic flaws coupon stacking, price and cart manipulation.
- Blunt bot-driven fraud credential stuffing and inventory hoarding.
- Protect accounts & card data to safeguard conversion and reputation.
PCI DSSSOC 2Insurance
Quote, bind and claims systems hold rich PII on fragile, integrated stacks.
- Find PII exposure across quote, policy and claims flows.
- Test the legacy stack the integrated systems scanners quietly skip.
- Stop fraud-enabling flaws in claims and payout workflows.
SOC 2
GDPRGovernment & Public Sector
Citizen data and critical services demand proof, not promises.
- Secure citizen-facing services and the sensitive data they process.
- Meet strict test mandates with clear, auditable, defensible reporting.
- Model real adversaries critical services mapped to MITRE ATT&CK.

OUR PROCESS
A tested process, not a scan-and-dash.
- ScopeTargets, access & rules of engagement. Signed scope + RoE
- ReconMap the real attack surface, the way an attacker would. Attack-surface map
- ExploitManual, hands-on testing. Flaws chained, impact proven. Verified findings
- ReportCVSS, proof, business impact & a concrete fix per finding. Board-ready report
- RemediateWe support your engineers through every fix. Prioritized roadmap
- RetestEvery fixed finding re-tested. At no extra cost. Closure, proven
WHY CYBROS
Senior testers. Real exploitation. Reports developers actually use.
Two minutes, straight from us: our mission, how we work, and why manual-first testing beats scan-and-dash.
- Manual-first testingHumans find the logic flaws and chained exploits scanners miss.
- Only senior testersEvery engagement is run by certified offensive-security pros. No juniors.
- Fix-focused reportingReproduction steps, CVSS and a concrete fix for every finding.
- Free retest includedWe re-test every fix at no extra cost, so closure is proven.
WHAT CLIENTS SAY
Trusted by the people who own the risk.
Our last vendor sent 40 pages of scanner output and called it a pentest. Cybros sat with our engineers, proved each issue with a real request, and gave us the fix line by line. We closed everything and their retest confirmed it. Completely different experience.
They found an access-control bug two previous tests had walked straight past, then hopped on a call to help our dev fix it. First security firm that actually felt like it was on our side.
No fear-selling. They told us two things we were worried about were not worth testing yet, which honestly earned my trust faster than any finding could have.
The report dropped straight onto our sprint board. Every finding had steps to reproduce and a clear fix, so there was nothing for the team to decode. We had patches out the same week.
PROOF
What we found, and what it prevented.
One over-privileged cloud role stood between an attacker and the whole environment.
Over-privileged role reachable via privilege-escalation chain
The API behind the app was leaking data and inventory through the front door.
BOLA / IDOR on order and profile endpoints
An IDOR that exposed every customer account, found and closed in twelve days.
Broken object-level authorization (IDOR) on the accounts API
SECURITY INSIGHTS
Practical writing from the people who do the testing.
What to do before your first penetration test
A practical preparation checklist for your first penetration test: how to scope it, prepare access, set rules of engagement, and plan for the fixes.
