SAST & secure code review
Automated static analysis plus expert manual review of authentication, crypto, and business-critical logic.
Offensive Security
Ship software that's secure by design
Build security into every commit. S-Security embeds SAST, DAST, manual code review, API security, WAF, and dependency scanning into your SDLC — catching vulnerabilities before they ship and protecting the apps already in production.
Overview
Fixing a bug in code costs pennies. Fixing it in prod costs a breach.
Your software is your front door. We make sure it doesn't have a hole in it — from the first line of code to the live API serving customers.
The cheapest, safest place to fix a vulnerability is in the IDE, not in an incident report. We shift security left without slowing your developers down.
S-Security embeds automated and manual security throughout your software lifecycle. Static analysis (SAST) and software composition analysis catch flaws and vulnerable dependencies as code is written; dynamic testing (DAST) and expert manual review probe running applications and APIs the way an attacker would; and a managed WAF protects what's already live. Findings flow into your existing tools — Jira, GitHub, GitLab — with the context and remediation guidance developers actually need to fix them fast.
- SAST — static analysis that finds flaws as code is written.
- DAST — dynamic testing of running apps and APIs.
- Secure SDLC — threat modeling and security gates in your pipeline.
- Manual code review — expert eyes on your most critical logic.
- API security — testing and protection for REST, GraphQL, and gRPC.
- WAF & dependency scanning — guard production and your supply chain.
What's included
Security across the whole SDLC
From design to deployment to runtime — automated where it should be, human where it matters.
DAST & runtime testing
Dynamic scanning and hands-on testing probe your running applications for exploitable flaws scanners can't reach alone.
API security
Discovery, testing, and protection for REST, GraphQL, and gRPC — including auth, rate-limiting, and business-logic abuse.
Dependency & SCA
Software composition analysis flags vulnerable and malicious open-source packages across your supply chain.
Managed WAF
A tuned web application firewall blocks live attacks against production while you remediate the underlying flaws.
Secure SDLC & threat modeling
We build threat modeling, security gates, and developer training into your pipeline so security scales with delivery.
How it works
Security woven into delivery
Threat model
We map how your application could be attacked before a line of code is written, so security is designed in, not bolted on.
Scan in the IDE & CI
SAST and dependency scanning run as developers commit, flagging issues with fix guidance right where they work.
DAST & manual review
Dynamic scanning and expert testing probe the running app and APIs for what automation alone would miss.
Gate & protect
Risk-based security gates block critical issues from shipping; a managed WAF shields production from day one.
Monitor & improve
Continuous runtime monitoring, metrics, and developer coaching steadily drive down your vulnerability backlog.
0

Why S-Security for AppSec
Developers' ally, not their blocker
Signal over noise
We triage and validate findings so developers get a short list of real, exploitable issues — not a scanner dump full of false positives.
In your workflow
Results land in GitHub, GitLab, and Jira with remediation guidance, so fixing security is just part of the normal sprint.
Humans where it counts
Automation scales coverage; our AppSec engineers manually review the auth flows and business logic that break the worst.
"S-Security caught a broken access-control flaw in our payments API during code review — the kind no scanner finds. They flagged it with a clear fix, and our team shipped the patch the same day."

FAQ
AppSec questions, answered
What's the difference between SAST and DAST?
SAST (static analysis) examines source code without running it, catching flaws early as code is written. DAST (dynamic analysis) tests the running application from the outside, like an attacker would, finding issues that only appear at runtime. They're complementary — we use both, plus manual review, for full coverage.
Will this slow down our release velocity?
No — that's the whole point of shifting left. Catching issues in the IDE and CI is far faster than finding them in production. We tune gates to block only genuinely critical issues and triage out false positives, so developers spend their time fixing real problems, not chasing noise.
Do you cover APIs and third-party dependencies?
Yes to both. We discover and test REST, GraphQL, and gRPC APIs for auth, access-control, and business-logic flaws, and our software composition analysis continuously flags vulnerable or malicious open-source packages across your supply chain.
Can a WAF replace fixing the code?
No — a WAF is critical protection, but it's a shield, not a cure. We use a managed WAF to block live attacks and buy you time, while the underlying flaw gets fixed in code. Defense in depth means doing both.
