What is Eresus Guard?

Eresus Guard is a commercial DAST and SAST platform from Eresus Security that finds vulnerabilities in web applications, APIs, and source code and backs findings with reproducible evidence.

Is Eresus Guard a web application firewall?

No. It is a vulnerability scanning and analysis platform. It tests applications for weaknesses; it does not sit inline and block traffic.

Can Eresus Guard find IDOR and broken authorization?

Yes. It supports multi-session authenticated API testing, which compares what different users can access to detect IDOR and authorization bypass.

Does Eresus Guard run offline?

No. There is no air-gapped license mode; every deployment connects to the online license service.

Eresus Security

Offensive security for web, API, cloud, and AI systems

Eresus Security is an offensive security company founded by Yiğit İbrahim Sağlam (ibrahimsql). It validates real attack paths across web applications, APIs, cloud environments, and AI systems, and reports findings that can be reproduced and fixed.

Eresus Guard

Enterprise application and API vulnerability scanning platform

Eresus Guard combines dynamic and static vulnerability scanning with multi-session authenticated API testing. It identifies security flaws across web applications, APIs, and source code with reproducible evidence.

What it does

235+ active and passive modules for web and API vulnerability testing.
Multi-session authenticated scanning for IDOR and authorization bypass.
SAST taint analysis, secrets detection, and SBOM export.
Out-of-band testing to verify blind vulnerabilities.
CI/CD integration with policy gates, exit codes, and SARIF export.

Who it is for

Application security and product security teams running continuous DAST/SAST and authorization testing.
Engineering and DevOps teams that want scan results and policy checks inside CI/CD pipelines.
Security organizations that need SSO/SAML, audit trails, and compliance reporting.
Managed security service providers (MSSPs) that manage many client tenants.

Who it is not for

Air-gapped environments: there is no offline mode, every deployment checks its license online.
Free or open-source tooling: Eresus Guard is commercial and closed source.
Web application firewall (WAF/IPS) needs: it tests for vulnerabilities, it does not block traffic.
Anyone expecting zero false positives with no human review: validation reduces noise, it does not remove the need for review.
Individual end users or consumer device protection: it is built for enterprise security teams.

License packages

Why we built Eresus Guard

The main problem in application security is rarely a lack of tools. It is results that do not match operational reality. Security and engineering teams usually hit three bottlenecks:

Fragmented tools and integration fatigue
Separate tools for DAST, source code analysis, dependency and secrets scanning leave teams with several interfaces, different data models, and integrations to maintain. Eresus Guard brings dynamic and static analysis into one platform with one data model.
False-positive noise
Scanners that report hundreds of theoretical, non-exploitable findings bury the real ones. Eresus Guard uses out-of-band interaction checks and reproducible HTTP evidence to reduce that noise and put verifiable findings first.
Modern API and authentication complexity
Catching broken function-level authorization (BFLA) and object-level authorization (IDOR/BOLA) requires testing as several users at once. Eresus Guard is built for multi-session authenticated testing in pre-production environments.

It is a security engineering product built on deterministic scan rules and bounded, verifiable automation, not on the idea that AI solves everything.
