Attack Before
They Do.

Our OSCP/OSCE-certified ethical hackers find every exploitable weakness across your web apps, networks, and cloud infrastructure — before a real adversary does. Detailed exploitation reports, not just scanner outputs.

Comprehensive Attack Surface Coverage

We test every surface an adversary would — web apps, APIs, internal networks, cloud configs, and the humans who use them.

01
🌐

Web App Penetration Testing

Full OWASP Top 10 coverage — SQLi, XSS, IDOR, SSRF, auth bypasses, business logic flaws, and JWT manipulation. Both black-box and white-box approaches.

02
📡

Network & Infrastructure Testing

External and internal network assessments — port scanning, service enumeration, lateral movement paths, Active Directory attacks, and domain privilege escalation.

03
☁️

Cloud Security Testing

AWS, Azure, and GCP configuration review — IAM privilege escalation, S3 bucket exposure, Lambda injection, misconfigured security groups, and container escapes.

04
📱

Mobile App Security Testing

iOS and Android binary analysis, reverse engineering, API testing, certificate pinning bypass, and data storage assessment following OWASP MASVS.

05
🎭

Social Engineering & Phishing

Spear phishing campaigns, vishing, and physical access simulations to test how well your team detects and resists human-centric attack vectors.

06
🔴

Red Team Operations

Full adversary simulation — TIBER-EU, CBEST, and custom threat actor emulations lasting weeks, testing your detection and response capabilities under realistic attack conditions.

Methodology

How We Run Engagements

Phase 01

Scoping & Reconnaissance

Define scope, rules of engagement, and threat actor profile. Passive OSINT, DNS enumeration, and attack surface mapping before any active testing.

Phase 02

Exploitation & Pivoting

Manual exploitation of discovered vulnerabilities, chaining multi-step attack paths, post-exploitation privilege escalation and lateral movement — fully documented.

Phase 03

Reporting & Remediation

CVSS-scored findings with full PoC evidence, business impact analysis, and step-by-step prioritised remediation guidance. Retest included within 30 days.

Why Gleyon Pentest

Real Hackers. Real Findings. Real Fixes.

We don't just run Nessus and print a PDF. Our testers manually chain vulnerabilities to show actual business impact — and stay available during remediation to answer developer questions.

  • OSCP, OSCE, PNPT, and CEH certified testers
  • Manual testing — not automated scanner outputs dressed up
  • Business-impact narrative alongside technical findings
  • Free retest of all critical/high findings within 30 days
  • NDA and evidence destruction post-engagement
  • Compliance-ready reports (ISO 27001, SOC 2, PCI-DSS)

Gleyon's pentest uncovered a SSRF vulnerability in our payment API that could have been used to exfiltrate card data. Their report was the clearest we'd ever received — each finding had exact code-level remediation steps. We were patched and retested within two weeks.
