Product Security Testing
If your team calls this VAPT, pentesting, a SaaS security assessment, or an independent security review, this is the place to start. We work within a defined scope, coordinate testing windows, and deliver clear findings with remediation guidance.
Clear scope. Fixed price. Predictable delivery.
Practice
10+ years in product security
The same practice shapes scope, tests the product, and defends the report in buyer and audit reviews.
Track record
700+ security engagements
Manual application, API, cloud, and AI assessments delivered with evidence, walkthroughs, and retest support.
Reach
150+ organizations secured
Used by SaaS, fintech, healthcare, and infrastructure teams that need a third-party review buyers can inspect.
Selected by product teams for scoped security testing
We model how real attackers move through a product - discovering assets, chaining weaknesses, and escalating access. That behavior shapes our testing sequence, so every finding maps to a realistic path and a concrete remediation step.
You get the evidence, the exact sequence, and a clear path to validation once fixes are in place.
Map exposed assets, enumerate APIs/domains, fingerprint frameworks, and probe defaults.
Evidence: Target inventory and risk notes captured in the engagement brief.
Threat-model product + environment. Align scope, assets, and abuse paths with your team.
Abuse permissive settings (CORS, storage ACLs, broad IAM) to gain a foothold.
Reproduce misconfig impact with sanitized PoCs/logs to demonstrate material risk.
Tighten policies; enforce least privilege; add config checks to CI.
Use IDOR/BOLA, weak validation, or undocumented endpoints to move laterally.
Demonstrate cross-tenant or privilege boundary breaks with minimal, reproducible requests.
Authorization guards, object ownership checks, strict schema/validation.
Convert partial access into higher privileges via token scope confusion or role misbinding.
Show exact sequence and tokens/claims enabling escalation.
Constrain scopes; validate roles server-side; rotate secrets after policy updates.
Reach sensitive data paths or control planes that affect customers or revenue.
Evidence: Screenshots, traces, sanitized PoCs included in the report.
Document impact, provide fixes, retest, and issue attestation.
Why teams trust the practice
Before teams commit, they usually check three things: who shaped the methodology, what public work exists, and whether the reporting holds up in real internal reviews.
Practice lead
Founder & CEO
Akash leads Appsecco's product security testing practice and the public research behind its methods, labs, and reporting standards.
The public body of work spans cloud attack training, MCP labs, and protocol-specific checklists. It shows how the team thinks before a statement of work ever gets signed.
AWS & Azure security training
949+ GitHub starsHands-on cloud attack-path training material that reflects the same operator mindset used in client cloud reviews.
Vulnerable MCP servers lab
157+ GitHub starsAn intentionally vulnerable MCP training lab that makes tool abuse, prompt injection, and boundary failures concrete.
MCP pentesting checklist
23+ GitHub starsA public checklist used by security teams to reason about tool safety, auth, transport, and data leakage in MCP systems.

What recent buyers say after the review
"The kind of vulnerabilities they found were things we never expected - things which were not on our radar. That changed how we think about our own attack surface."
Founder & CEO
Asia's leading Threat Intel Company
"Found multiple interesting exploitable vulnerabilities across our product. Clear reporting, thorough walkthroughs of each finding, and they stayed engaged until every issue was resolved."
Manager
Most popular Vulnerability Scanner (100+ countries)
"We engaged with Appsecco for red teaming. Their findings were specific, well-documented, and gave our team a clear path to remediation."

Reference-ready next step
Start with the product area that matters and we will send the most relevant report sample, case study, or public research reference.
Share the environment you are reviewing and we will point you to the most relevant case study, report example, or public research trail.
Request scoped reviewNo commitment required. We will outline a scoped next step and confirm whether a fixed-price assessment makes sense.
A fixed-scope, fixed-price engagement with a short, predictable sequence. We confirm targets, testing windows, and reporting format before any testing begins.
We agree on in-scope assets, environments, and rules of engagement. You see exactly what will and will not be tested.
Testing happens in the agreed window with coordination points to avoid disruption and keep teams informed.
Findings include clear evidence and remediation steps. We map each fix to the same path used to validate it.
We review results, answer questions, and deliver a report that is ready for internal and compliance reviews.
Each third-party pentest or VAPT engagement produces clear evidence, prioritized fixes, and review-ready summaries. The coverage below shows where we test; the deliverables stay consistent across every area.
SaaS VAPT, web application penetration testing, API pentesting, and business logic testing for product teams.
We review cloud and cluster configurations for real exposure paths and explain how to close them without disrupting operations.
We test AI integrations and MCP workflows and describe how to reduce misuse without blocking product goals.
VAPT reports, pentest attestations, and evidence packages for engineering, security, customers, and auditors.
Designed to make internal reviews straightforward without adding extra work.
Safe next step
Share what you want tested and any timelines you are working within. We will outline a careful, fixed-scope approach and answer questions before you decide anything.
