Security Testing (VAPT) › API Security Testing
API Security Testing — Your API is the real attack surface — test it directly
Most breaches today happen through APIs, not the UI in front of them. SIRI Security tests your REST, GraphQL or SOAP APIs directly against the OWASP API Security Top 10, independent of whichever frontend happens to call them.

Effective
31 JUL 2026
RBI's 2026 Framework requires commercial banks to run and evidence regular security testing as part of a continuous assurance programme, not a one-off exercise.
Named standard
OWASP TOP 10
Application and API testing scoped against the current OWASP Top 10 and OWASP ASVS remains the reference baseline auditors and regulators expect to see.
Growing gap
62% CLOUD
Cloud misconfiguration and IAM exploitation account for 62% of detections in cloud environments (DSCI) — testing scoped to on-premises infrastructure alone misses most of current risk.
Baseline
70% MALWARE
Trojans and file infectors make up 70% of malware detections (Seqrite 2026) — the entry point most exploitation testing has to account for.
Evidentiary bar
6 HR WINDOW
CERT-In's breach-notification window depends on already knowing your exposure — tested, documented findings are what makes that deadline realistic to meet.
Testing evidence, not a scan report
What is API Security Testing?
API security testing treats the API as the primary target rather than a byproduct of testing the app in front of it. That matters because APIs are increasingly called by mobile apps, partner integrations, and third-party services that never go through your web UI at all — and object-level and function-level authorization flaws in the API are invisible from the frontend.
We test for broken object-level authorization (can user A fetch user B's data by changing an ID), broken function-level authorization (can a normal user call an admin endpoint), excessive data exposure, mass assignment, rate-limiting gaps, and the rest of the OWASP API Security Top 10 — across REST, GraphQL, and SOAP.
Scanners find the obvious; testers find what gets you breached
62% of cloud detections trace to misconfiguration and IAM exploitation (DSCI) — exactly the class of issue automated scanning alone tends to miss.
SIRI Security delivers API Security Testing to this standard directly — practitioner-led, documented, and connected to SIRI Law LLP's legal and regulatory response if a finding ever needs to go further.
What organisations get wrong
Four assumptions that leave real exposure untested
A scanner report and a genuine security test are not the same evidence — and auditors increasingly know the difference.
01 — TOOLING
“We ran an automated scan, so we're covered”
Automated tools catch known signatures; they consistently miss business-logic flaws and chained vulnerabilities a human tester finds by thinking like an attacker.
02 — SCOPE
“Our last test covered the main system”
New features, integrations, and cloud services ship continuously — a test scoped a year ago doesn't speak to what's live today.
03 — EVIDENCE
“We fixed the findings, so we're done”
Without a documented retest, there's no evidence the fix actually worked — which is exactly what an auditor or insurer will ask for.
04 — FRAMING
“A clean report means we're secure”
A test result is a point-in-time statement about what was in scope — not a permanent guarantee, and not a substitute for ongoing monitoring.
What API Security Testing covers
What's included, start to finish
Deployed once per engagement, documented to a standard auditors and insurers actually accept.
01
OWASP API Top 10 coverage
Broken object/function-level authorization, excessive data exposure, mass assignment, and more.
02
Authentication & token testing
JWT handling, token expiry, refresh-token abuse, and API key management.
03
Rate limiting & resource exhaustion
Whether the API can be abused to exhaust backend resources or bypass throttling.
04
Schema & documentation review
Swagger/OpenAPI or GraphQL introspection reviewed for accidental over-exposure.
05
Third-party integration testing
Webhooks and partner-facing endpoints tested with the same rigor as internal ones.
Evidence, not guesswork
Unscoped internal effort vs. a documented SIRI engagement
The gap is rarely the tooling — it's whether the result holds up as evidence.
| Approach | No dedicated testing | Ad hoc internal effort | SIRI API Security Testing |
|---|---|---|---|
| Methodology | None | Varies by who ran it | OWASP / CREST-aligned, documented |
| Manual exploitation | No | Rare | Included as standard |
| Evidence for auditors/insurers | None | Inconsistent | Formal report + CVSS ratings |
| Retest on fixes | N/A | Rarely tracked | One free retest cycle included |
| Satisfies RBI/SEBI testing expectations | No | Partially | Yes, when scoped to your entity category |

Numbers every board should know
What testing is actually catching
62%
Of cloud detections
Trace to misconfiguration and IAM exploitation (DSCI) — the category testing has to explicitly cover.
70%
Of malware detections
Are trojans and file infectors (Seqrite 2026) — the entry point most exploitation chains start from.
29.44L
Incidents CERT-In handled
In the latest reporting year — the scale of activity testing exists to reduce a share of.
6 HR
CERT-In notification window
Runs from discovery — tested, documented exposure is what makes that window realistic to meet.
Why SIRI for API Security Testing specifically
Testing connected directly to legal and response, not a separate vendor
The same roof runs the test, the fix verification, and — if a real finding turns into an incident — the legal response.
01
Findings connected directly to legal exposure
SIRI Security runs under the same roof as SIRI Law LLP — when a finding carries real legal exposure, the engagement can be brought under attorney-client privilege from day one, not bolted on after the fact.
02
Led by named practitioners, not a rotating bench
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
03
Court-admissible evidence when it matters
Ananya Krishnan, SIRI's Digital Forensics Lead, prepares court-admissible forensic reports and testifies as an expert witness when findings end up in front of a judge.
04
Built for RBI and SEBI's specific evidentiary bar
Testing is scoped and documented to the standard RBI's 2026 Framework and SEBI's CSCRF expect from regulated entities, not a generic vendor template.

How we work
From scoping to ongoing delivery
01
Scoping & Threat Modeling
We map the API attack surface with you, agree on rules of engagement, and build a threat model around what an attacker would actually go after first.
Week 102
Manual + Automated Testing
Our testers combine automated scanning with hands-on manual exploitation against the API, since scanners alone miss business-logic and chained vulnerabilities.
Weeks 2–303
Reporting & Risk Rating
Every finding is written up with proof-of-concept, CVSS scoring, and business impact — not just a raw scanner export — so your team can prioritise by risk, not by noise.
Week 4+04
Remediation & Free Retest
You fix the findings with our guidance, and we retest the fixed issues at no extra cost before issuing the final clearance report.
OngoingFrequently asked
API Security Testing, answered directly
Do you test GraphQL differently from REST?
Yes — GraphQL introspection, query depth/complexity abuse, and batching attacks are tested specifically, on top of the standard authorization checks.
Can this run alongside our CI/CD pipeline?
The manual engagement itself is scheduled, but the same team can help wire automated API security checks into your pipeline afterward under our DevSecOps service.
How long does an engagement take?
Most single-application or single-network engagements run 5 to 10 business days depending on scope, with the report and retest typically following within another week.
Is the retest really included at no extra cost?
Yes. One full retest cycle on the issues we found is included in every SIRI Security VAPT engagement — we don't charge again to confirm you fixed what we flagged.
Close the evidence gap
Scope API Security Testing.
Most engagements start with a short scoping call to confirm environment, timeline, and rules of engagement.
