Testing Every Layer
Of Your Attack Surface

Engagement Dossier
Exploitable findings only

Manual testing across reconnaissance, initial access, lateral movement, and persistence. Every finding is walkthrough-documented with PoC, affected assets, CVSS 3.1 scoring, and owner-ready remediation. No false positives.

Scope Definition
Target IP ranges, domain names, cloud accounts, API endpoints, test windows, payload safeguards (no data exfil, no ransomware), and emergency stop contact.
PoC Documentation
HTTP request/response chains, CLI command sequences, Burp repeater tabs, code snippets for exploitation, and before/after screenshots from target system.
Risk Translation
CVSS 3.1 base/temporal/environmental scores, business impact narrative, exploitability chain (how attacker chains findings for larger breach), and time-to-fix estimates per severity.
Remediation Workflow
Code patch or configuration change required, owner assignment by team, validation testing steps, and regression risk assessment. Includes retest pass/fail criteria.

Our Process

How We Operate

01
Scoping
Target IP ranges/hostnames, DNS domains, AWS/GCP project IDs, API endpoints, authentication credentials, test windows (no production impact times), payload restrictions (no data exfil, no permanent changes), emergency shutdown contact, legal agreements signed, insurance verified, and incident response plan reviewed.
02
Reconnaissance
Passive: Shodan/Censys IP enumeration, DNS zone transfers, GitHub secret scanning, WHOIS/ASN lookups. Active: Port scanning (Nmap top-1000), service version enumeration, Web application fingerprinting (Wappalyzer), SSL/TLS certificate chain analysis, hidden endpoint discovery (Subfinder/Amass).
03
Exploitation
Manual validation of automated scanner findings. Chaining findings (e.g., IDOR → RCE). Testing business logic flaws. Bypassing authentication mechanisms. Crafting payloads for injection attacks. Exploiting race conditions. Fuzzing for unexpected behaviors. No destructive payloads — data extraction only for PoC.
04
Post-Exploit
Privilege escalation (kernel exploits, sudo misconfig). Lateral movement (credential spraying, VLAN hopping, token theft). Persistence mechanisms (cron jobs, scheduled tasks, backdoor accounts). Data exfiltration simulation (not executed). Detection evasion testing (log cleanup, firewall bypass, beacon concealment).
05
Reporting
Executive Summary (business risk, remediation cost). Technical Report per CVSS 3.1 (base/temporal/environmental scores). For each finding: vulnerability description, affected assets, reproduction steps, HTTP requests, code screenshots, CVSS rating, CWE reference, remediation code/config, retest date. Appendix: Tools used, test coverage gaps, assumptions.

Why Adversyl

No Automated
Scanner Dependency

100% Manual Testing
Every assessment is performed by humans, not scanners. We find logic flaws and chained exploits that automated tools miss entirely.
72-Hour Quick Start
From signed agreement to active testing within 72 hours. Rapid mobilization for urgent security assessments and incident response.
Certified Professionals
All testers hold OSCP, CEH, CREST, or CISSP certifications. Active bug bounty hunters with real-world exploit experience.
Actionable Reports
No jargon-filled PDFs. Clear risk ratings, PoC evidence, remediation steps, and a retest included in every engagement.

FAQ

Common Questions

What do we receive at the end of a test?

An executive summary covering business risk and remediation cost, plus a technical report. Each finding includes a description, affected assets, reproduction steps, the HTTP requests, a CVSS 3.1 rating, a CWE reference, the fix, and a retest date.

How quickly can testing start?

We scope your request within 24 hours. Once the agreement is signed, active testing starts within 72 hours.

Will testing disrupt our production systems?

Testing runs inside the rules of engagement you sign: agreed test windows, IP ranges, API rate limits, no destructive payloads, and an emergency stop contact on your side.

Is a retest included?

Yes. A retest is included in every engagement and is scheduled within 14 days of the fixes, with clear pass or fail criteria for each finding.

Do you rely on automated scanners?

No. People run every assessment. Tools speed up discovery, but each finding is confirmed by hand with a working proof of concept, so you receive no scanner noise or false positives.

Who performs the testing?

Testers who hold OSCP, CEH, CREST or CISSP certifications, and who are active bug bounty hunters with real-world exploit experience.
