Vulnerability
Research.
Automated scanners find what is known. Our team finds what is unique to your architecture. With 25 years of offensive security experience behind every engagement, we go where tools cannot reach.
"An automated scanner is like a metal detector at an airport. It will flag a knife in a bag. It will not notice the person who has memorised the emergency exit codes and knows which fire door is left unlatched every morning. That is the gap we were built to close."
Security tools cover the known. Your most serious vulnerabilities are the ones that only become visible when a human who thinks like an attacker sits down and spends time inside your application. A logic flaw in how your payment flow handles refunds is not in any CVE database. It will never appear in a scanner report. But it is there, and someone with enough patience will find it before you do.
What scanners
will never find.
These are the categories of vulnerability that exist in nearly every production application and that automated tools reliably miss because they require human reasoning to identify.
Authorisation flaws hidden in workflow
Your access controls work correctly when tested in isolation. But when a user completes step 3 before step 1, or submits a request with a role they held last month, or calls endpoints in an order your team did not anticipate — the controls collapse. A scanner follows the happy path. It does not invent attack sequences.
BOLA and mass assignment at scale
Broken Object Level Authorisation is the most common serious API vulnerability and among the least likely to be caught by a tool. It requires testing every object reference against every role and understanding which data relationships make cross-account access meaningful. That reasoning cannot be scripted.
Trust boundary assumptions in microservices
In a microservices environment the internal network is often implicitly trusted. Services talk to each other without re-validating identity. If an attacker compromises one service they can often move laterally to others that assume internal traffic is safe. This is an architectural pattern not a code defect and scanners have no way to reason about it.
Race conditions and time-of-check flaws
A user submits two simultaneous withdrawal requests each within the balance threshold. Both pass the balance check. Both succeed. The balance goes negative. This class of vulnerability requires understanding the timing and state implications of concurrent operations — something that requires a human to model correctly and reproduce deliberately.
Six threat
vectors.
One team.
Each capability below is delivered by the same offensive operations team rather than outsourced to a different vendor for each discipline. Context carries across your engagement.
Web Application VAPT
Deep manual testing that goes well beyond the OWASP Top 10. We focus on complex business logic, multi-step authorisation flows, second-order injection, and data integrity issues that automated tools cannot reason about.
Mobile App Security
Full-spectrum audit of iOS and Android applications. We test local storage encryption, SSL pinning implementation, inter-process communication security, binary protection, and the server-side API surface that mobile clients expose.
API Security Audits
Comprehensive security review of REST, GraphQL, and gRPC interfaces. We identify BOLA, mass assignment, unauthenticated endpoint exposure, excessive data exposure, and rate limiting gaps across the full API surface including undocumented endpoints.
Thick Client Testing
Specialised security analysis of legacy and modern desktop applications. We perform binary reverse engineering, memory forensics, DLL hijacking analysis, inter-process communication audits, and local privilege escalation testing on Windows and Linux clients.
Cloud Configuration Audit
Infrastructure-as-Code and runtime audit across AWS, Azure, and GCP. We review IAM policies for least-privilege compliance, network perimeter configurations, S3 bucket exposure, secrets management, and logging gaps that would allow undetected lateral movement.
Compliance Readiness
Technical gap analysis mapped against ISO 27001, SOC 2, and the DPDP Act. We translate compliance requirements into concrete security controls, produce evidence-based audit trail documentation, and issue a formal Attestation of Security upon re-validation completion.
Four phases.
No shortcuts.
Every engagement follows a strict adversarial framework built on OSSTMM, OWASP, and NIST standards. The order of phases is not arbitrary. Each builds on the intelligence gathered in the one before it.
Passive and active mapping of the entire digital footprint. We identify all domains and subdomains, enumerate exposed endpoints and APIs, map third-party integrations, and surface shadow IT that the organisation may not know exists. Nothing is in scope until we understand the boundaries.
The core manual phase. Our engineers use custom tooling alongside deep manual analysis to uncover vulnerabilities in business logic, authorisation flows, and implementation. We do not run a scanner and report what it finds. We follow chains of logic the way an attacker would.
Every significant finding is validated with a working proof of concept demonstrating the real-world impact. We show what an attacker could actually do with each vulnerability — not just that it exists. This changes the conversation from theoretical risk to demonstrated business impact.
Not a bug list. We provide architectural guidance and specific code-level fixes for each finding. After your team implements the remediations we conduct a re-validation phase to confirm each vulnerability has been correctly closed. The engagement ends with a formal Attestation of Security document.
Immediate action required. Three unauthenticated admin endpoints can be reached from the internet with no authentication challenge. This was the first finding in recon and was escalated to the client before the formal vulnerability research phase began.
13 findings total across 2 critical, 4 high, 7 medium severity. The BOLA and JWT vulnerabilities were identified through manual logic testing. Neither appears in automated scan output from the client's existing tooling. Full report delivered with working proof of concept for every finding.
Business impact demonstrated. Any authenticated user can read the complete order history, PII, and partial payment data of any other user by iterating the user ID parameter. The object reference is sequential and predictable. Full account enumeration is possible.
Re-validation scheduled at week 4. All critical and high findings must be remediated before we issue the Attestation of Security document. We will verify each fix with a targeted test rather than a full re-run so your team is not blocked for two weeks.
