The Caesars
Praetorian's Roman-named capabilities that Guard runs, such as Brutus, Julius, Titus and Trajan, many of them open source, plus Knossos deception environments.
- Augustus: LLM Vulnerability ScannerAugustus is an LLM vulnerability scanner that tests AI systems for jailbreaks, prompt injection, MCP server security, and other attack techniques across a broad range of model providers.
- Aurelian: Multi-Cloud Security ReconnaissanceAurelian is an open-source, multi-cloud security reconnaissance framework that enumerates cloud resources, detects misconfigurations, finds secrets, and identifies privilege escalation paths across AWS, Azure, and GCP.
- Brutus: Modern Credential Attack TestingBrutus is a credential testing capability in the Praetorian Guard Platform supporting 43+ protocols, a cumulative credential corpus for cross-service reuse testing, account enumeration with named results, and seamless pipeline integration.
- Constantine: Locates Fatal Security Bugs in Software & Code Repository Security AnalysisHow to use Constantine's autonomous vulnerability discovery and patching engine, and its code repository security analysis capability — including CVE benchmark coverage, LLM-driven entrypoint discovery, the agentic threat-hunting agent, proof-of-exploitation lifecycle tabs, build caching, repository security review workflow, and scored repository findings via the CLI and MCP server.
- Hadrian: API Security TestingHadrian is a security testing framework for REST, GraphQL, and gRPC APIs that tests for OWASP API vulnerabilities using role-based authorization testing and YAML-driven templates.
- Julius: LLM Service FingerprintingHow Julius, Praetorian's open-source tool, identifies the LLM serving software, such as Ollama or vLLM, behind an endpoint.
- Nerva: Service FingerprintingNerva is Guard's network fingerprinting engine — identifying services, extracting versions, and correlating CVEs across your attack surface.
- Pius: Attack Surface MappingHow Pius, the open-source tool behind Guard's asset discovery, maps your domains, subdomains, and IP ranges.
- Titus: Secrets DiscoveryTitus is Praetorian Guard's purpose-built secret scanner, providing automated continuous secret discovery, validation, and on-demand credential analysis across your attack surface.
- Trajan: CI/CD Pipeline AttacksTrajan scans GitHub Actions, GitLab CI/CD, and Azure DevOps pipelines for supply-chain and CI/CD security risks, surfacing misconfigurations, excessive permissions, and exploitable vulnerabilities — and can now run as a native GitHub Action with verification chains for confirmed findings.
- Vespasian: API Discovery and Specification GenerationVespasian discovers API endpoints from captured traffic and generates REST, GraphQL, SOAP, and WebSocket specifications, including SPA endpoints recovered via JS static analysis in fully offline capture-once/generate-many workflows.
- Caligula: Software Supply Chain Security ScannerCaligula scans software supply chains for known vulnerabilities, malicious packages, compromised AMIs, and IaC image references across 7 ecosystems and 12 manifest formats, integrated natively into Guard.
- Probus Web Application Attack SurfaceAutomated tier-one web application vulnerability discovery powered by the Probus adapter, with API fuzzing findings surfaced in Guard.
- Knossos: Deception EnvironmentsKnossos procedurally generates realistic decoy cloud environments so attackers waste time in fake infrastructure instead of yours.
