Find what scanners miss. Fix it before launch.
Expert-led penetration testing that simulates real-world attacks on your web applications and APIs. OWASP Top 10 plus manual exploitation, with proof-of-concept evidence and re-test included.
Let's talk
The situation
Most attackers do not break in. They walk through the front door because no one checked if it was locked.
The numbers
$4.9M average cost of a data breach (IBM Security, 2024).
287 days to identify and contain a breach without proactive testing.
+40% rise in cyber attacks year-on-year (ENISA, 2024).
3x ROI of preventive security testing vs. post-breach costs.
Who is exposed
SMEs and scale-ups without in-house security teams. SaaS platforms where a breach means immediate churn. Regulated industries under GDPR, NIS2, and ISO 27001. Pre-launch products shipping to thousands of users.
What you will know
Every public-facing vulnerability identified and validated with proof-of-concept evidence.
Risk rating (Critical, High, Medium, Low) with business impact in plain language.
A prioritised remediation roadmap: what to fix first.
Clear separation of compliance-critical vs. advisory findings.
Free re-test of all critical and high findings.
Executive Risk Summary ready for the board, plus technical detail for your dev team.
Sample reports from a real penetration test
Unauthorized Account Takeover via file upload (Critical): unauthenticated payload uploaded, admin session hijacked via social engineering link.
Privilege Escalation and Mass Data Exfiltration (Zero-Day): lowest-privilege HR account extracted entire staff database, salaries, passwords, personal data.
Business Logic Vulnerability, Price Manipulation (Critical): negative quantities bypassed server validation, bookings completed at zero cost.
How it works
Scoping
Kickoff, scope confirmation, attack surface mapping, emergency contacts.
Scanning and exploitation

Why Gradion
Red Team expertise, not just tooling
OWASP Top 10 and Burp Suite Pro is the baseline, not the finish line. Every engagement includes manual expert exploitation. Logic flaws, API abuse chains, and session vulnerabilities that automated scanners miss.
Two depths, one expert team
Standard (Black/Grey-Box) for compliance baselines and pre-launch checks. Deep Dive (White-Box) for source code review, architecture analysis, and insider-threat simulation. Same team, matched to your risk level.
Proof-of-Concept evidence, always
Every finding backed by a working PoC exploit. Reports in plain English for the board and precise code-level guidance for developers. Re-test included.
Web Application Penetration Test
Fixed price. No surprises.

Common questions
We had a pentest done last year. Do we need another one?
Yes, if your codebase, infrastructure, or APIs have changed since then. Penetration testing is only valid at the point it was conducted. New features, integrations, and dependency updates introduce new attack surfaces. Annual testing is the minimum standard for most compliance frameworks.
How disruptive is the testing process?
For Standard, we need URL access, a staging environment, and a technical point of contact. Your dev team is involved at kickoff and debrief only. For Deep Dive, we need read-only source code access and 2-3 hours of availability across the engagement.
What if you find something critical during the test?
We notify your technical lead immediately. We do not wait until the final report. You are never left exposed while we finish documentation.
How is this different from an automated scan?
Automated scanners find known patterns. Our Red Team finds logic flaws, chained vulnerabilities, and business-context exploits that no scanner catches. Every finding includes a working proof-of-concept, not a severity score on a spreadsheet.
What comes next
Penetration test findings feed directly into Web Security Hardening (EUR 4,999-6,999). We fix what we find, deploy WAF protection, and re-test to confirm every gap is closed.
For cloud environments, the Cloud Security Assessment (EUR 5,999-6,999) extends coverage beyond the web tier.
No obligation to proceed. The pentest report stands on its own.
Web App Penetration Test: from EUR 5,000
