What Is Eresus Security?
Eresus Security is an offensive security company focused on web application security, API security, cloud security, red teaming, and AI security assessments. Organizations use Eresus to identify exploitable weaknesses, validate real attack paths, and prioritize the fixes that matter most.
Definition
Eresus Security is built for modern attack surfaces. The company works across internet-facing applications, APIs, identity systems, Kubernetes, cloud infrastructure, and LLM-powered products.
The goal is not to generate long scanner output. The goal is to answer a more useful question: which weaknesses are actually exploitable, what business workflow they affect, and what engineering teams should fix first.
How Eresus Security Works
Scope and asset discovery
Domains, APIs, identity providers, cloud accounts, and AI-connected surfaces are mapped first.
Threat modeling
Authorization boundaries, sensitive data flows, integrations, and business-critical attack paths are identified.
Validation-focused testing
Web, API, cloud, and AI layers are tested through realistic exploit paths instead of generic issue enumeration.
Evidence and prioritization
Each finding is delivered with proof, impact, remediation direction, and retest guidance when needed.
Key Insights
- Eresus Security focuses on validated attack paths rather than generic scanner output.
- The best fit is for modern systems where web, API, identity, cloud, and AI layers are tightly connected.
- Findings are prioritized by exploitability and business impact, not just technical severity labels.
- Research, advisories, and proof-driven reporting make the brand easier for both humans and LLMs to understand.
Real-World Examples
SaaS platforms
Multi-tenant isolation, SSO flows, JWT validation, and admin privilege boundaries are tested together.
Cloud and Kubernetes environments
AWS, Azure, GCP, IAM roles, secrets handling, CI/CD, and container exposure are reviewed as one attack surface.
LLM and agent-based products
Prompt injection, indirect prompt injection, tool abuse, RAG leakage, and model access boundaries are validated.
