Web and API Penetration Testing
Methodical testing aligned with the OWASP Testing Guide, NIST SP 800‑115, and OSSTMM.
- 01
Pre‑engagement and scoping
- Agree on scope, objectives, rules of engagement, stakeholders, and timelines.
- Confirm in scope applications, environments, and technologies, define test accounts and data handling.
- 02
Information gathering (reconnaissance)
- OSINT, technology enumeration, endpoints and API discovery, role and permission mapping.
- Attack surface mapping to identify likely entry points.
- 03
Threat modeling and vulnerability discovery
- OWASP category analysis and abuse case brainstorming.
- Automated scanning with tools such as Burp Suite, OWASP ZAP, and Nessus, followed by deep manual verification.
- Identify misconfigurations, insecure coding patterns, and logic or authorization issues.
- 04
Exploitation (safe and controlled)
- Validate impact without service disruption: SQL injection, cross site scripting, authentication bypass, IDOR, SSRF, privilege escalation, session weakness.
- Correlate and duplicate findings from tools and manual testing.
- 05
Post‑exploitation and risk analysis
- Assess pivot and lateral movement potential, data exposure, and persistence opportunities.
- Map technical issues to business impact and prioritize remediation.
- 06
Reporting and recommendations
- Executive summary for leadership.
- Technical report with proof of concept, evidence, and CVSS based severity.
- Step by step remediation guidance, secure patterns, and references.
- Live readout workshop with engineers and security stakeholders.
Deliverables
- Executive report
- Detailed technical report
- Jira ready tickets
- Proof of concept artifacts
- Remediation clinic
Service pillars
Risk and Security Posture
- Product and enterprise risk assessments
- Control framework mapping (OWASP ASVS, CIS, NIST)
- Architecture and identity reviews (Zero Trust, SSO or MFA, privileged access management)
Outcomes
Prioritized risk register, a 30, 60, 90 day roadmap, quick wins and strategic steps.
Resiliency Testing
- Web, API, and mobile testing
- External attack surface assessment
- Cloud security reviews and offensive tests that focus on misconfigurations and IAM
- Red and purple team exercises, adversary emulation, phishing simulations
Outcomes
Validated controls, evidence based risk reduction, measurable improvements to resilience.
How we work
Engagement models
- Point in time assessments: Fixed scope tests and reviews.
- Flex retainer: A set number of monthly hours for tests, reviews, and advisory.
- Program partnership: Roadmap with OKRs, quarterly test cycles, and continuous improvement.
Collaboration
Shared communication channels, weekly standups, a shared backlog, and a secure evidence vault.
