Application Security
Application security and secure SDLC
Threat modeling, secure code review, and CI/CD gates for release cycles.
We embed AppSec into your SDLC: architecture threat models, tuned SAST/DAST/SCA gates, manual review of auth and payment paths, and API abuse testing — with findings delivered as PR comments and fix snippets your developers can merge.

What AppSec covers
Application security is a program, not a scan. We combine manual secure code review of your critical paths, automated SAST/DAST/SCA tooling tuned to your stack, API security testing and SDLC consulting — design threat modeling, security requirements, pipeline gates and developer enablement. The goal: vulnerabilities found in minutes at commit time, not months later in production, with fixes that arrive as pull-request comments your developers actually read.
When teams engage us
The earlier a defect is found, the cheaper it is to fix — a production vulnerability costs far more than the same flaw caught in code review. Yet most teams rely on a yearly pentest while shipping weekly. Our AppSec program shifts security left: every pull request scanned, every release gated, every developer trained, every API continuously tested. Security becomes a property of your pipeline instead of an annual event.
True shift-left
Security gates in CI/CD that block critical issues without blocking the business.
Developer-friendly findings
Issues arrive as PR comments with fix snippets — not PDF reports nobody reads.
API-first coverage
REST, GraphQL and event-driven architectures tested for business-logic abuse.
Security champions
We train internal champions who keep the program alive between our engagements.
Yearly pentests do not cover weekly releases.
Threat models on new features, pipeline gates tuned to your stack, manual review of critical paths, and developer training on the flaw classes we find in your code — so security keeps pace with your sprint cadence.
Model, gate, review, test, enable.
Five phases · 2–4 weeks setup · ongoing cadence · each phase ends with named outputs you can hold us to.

Architecture & threat modeling
We model trust boundaries, data flows and abuse cases for your application — producing security requirements developers can implement, not generic checklists.
- Threat model
- Security requirements
- Abuse-case catalog
Pipeline integration
SAST, DAST, SCA and secret scanning deployed into CI/CD and tuned to your stack — gates set to fail on critical and high findings in changed code only.
- Configured security gates
- Tuned rule baseline
- Pipeline gate policy
Manual secure code review
Expert review of authentication, payments, access control and other critical paths — the business-logic flaws no scanner can see.
- Critical-path review findings
- Fix guidance with snippets
- Severity-ranked issue list
Dynamic & API testing
Running-app testing of business logic, API abuse, client-side risks and race conditions against staging — with reproduction steps your engineers can follow.
- Dynamic test report
- API abuse-case results
- Reproduction steps
Enablement & champions
Developer training on the flaw classes we found in your code, a security champions program, and quarterly metrics that show the program working.

What we test and harden
Flaw classes and disciplines we prioritize on every appsec engagement.
Threat modeling
Structured analysis of new features before code exists — the cheapest moment to find design flaws.
SAST/DAST/SCA integration
Scanners tuned to your stack with severity-based gates, so findings are trusted instead of ignored.
Secure code review
Manual expert review of authentication, payments, authorization and other logic where scanners are blind.
API security
REST, GraphQL and event-driven APIs tested for BOLA, mass assignment, excessive exposure and rate-limit abuse.
CI/CD security gates
Pipeline hardening, artifact signing and branch protection — supply-chain controls that do not slow releases.
Secrets scanning
Credentials caught at commit time, with rotation runbooks for what already leaked.
Dependency hygiene
SCA with reachability analysis — upgrades prioritized by whether your code actually calls the vulnerable path.
Developer training loop
Every review finding becomes a training example — the loop that shrinks whole flaw classes over quarters.
Tools we use on this work
What you receive
Named artifacts you can open, share with auditors, and hand to engineering — not vague promises.
Threat model document
Trust boundaries, data flows and security requirements for your application architecture.
Tuned pipeline gates
SAST, DAST, SCA and secret scanning configured with a gate policy your team agrees to.
Critical-path code review
Manual findings with fix snippets, delivered as PR comments developers actually read.
API & business-logic test results
Abuse-case testing with reproduction steps and severity ratings.
Security champions playbook
Structure, training plan and office-hours model to sustain the practice internally.
Quarterly program metrics
MTTR, defect escape rate and coverage trends that prove the program's value to leadership.
What we typically confirm
Flaw classes we most often validate on this engagement type — so scope conversations stay realistic.
Authorization checks missing on API endpoints the frontend never calls
Dependency vulnerabilities with known exploits reachable from exposed code paths
Secrets committed to repositories and never rotated
Mass-assignment flaws in framework-heavy backends
Rate limiting absent on authentication and data-export endpoints
Server-side validation trusted to the client for critical business rules
CI/CD pipelines deployable by any developer with repo access
Verbose stack traces and error messages leaking internals to users
What we need from you
A short checklist so kickoff is not delayed. Most items take under an hour — and everything shared is covered by NDA from the first call.
Repository access with read permissions for reviewing engineers
A staging environment dynamic testing can safely target
CI/CD admin access (or a pairing engineer) for pipeline integration
Architecture overview and data-flow context for threat modeling
A named engineering liaison for findings triage
Agreement on gate policy — which severities block a release
AppSec FAQ
No — that's a design failure. We tune gates to fail only on critical/high findings in changed code, with a 1-day triage SLA so teams are never blocked on false positives. Most clients see release times unchanged within two sprints.
