The Challenge
Businesses across the United States face an escalating cybersecurity crisis. Ransomware attacks have surged 95%, the average cost of a data breach has reached $4.88 million, and 43% of all cyberattacks now target small and mid-size businesses. Most devastating of all, 60% of SMBs that suffer a major breach close their doors within six months.
Compounding the threat landscape is a cyber insurance crisis: 41% of applications are denied due to inadequate security controls, and premiums have doubled over the past two years. Traditional compliance tools and penetration tests cost anywhere from $7,000 to $80,000+, take 4 to 8 weeks to complete, and most SMBs lack the dedicated security teams to interpret the results — let alone act on them.
Escalating Cyber Threats
Ransomware up 95%, $4.88M average breach cost, 43% of attacks targeting SMBs, and 60% of breached SMBs closing within six months — the threat landscape is accelerating faster than most businesses can respond.
Cyber Insurance Crisis
41% of cyber insurance applications are denied outright due to missing security controls like MFA, DMARC, EDR, and encrypted backups — leaving businesses financially exposed to catastrophic losses.
Prohibitive Cost & Timeline
Traditional penetration tests cost $7,000 to $25,000, comprehensive compliance audits run $30,000 to $80,000+, and both take 4 to 8 weeks — pricing out the very organizations most at risk.
No Dedicated Security Teams
Most SMBs lack in-house cybersecurity expertise. They depend on IT generalists or outsourced MSPs who may not specialize in compliance frameworks, insurance requirements, or emerging threat vectors.
The Solution
Sigma Agents built an autonomous agentic cybersecurity platform for Sentinel Health Compliance — a fully self-operating AI system deployed at cyberdefenseagent.ai that autonomously scans, scores, maps compliance, and generates actionable intelligence without human intervention.
The platform operates as a true agentic system — it does not simply present data for humans to interpret. It autonomously executes a 100-tool external attack surface analysis in 60 seconds, generates a Cyber Defense Score (A through F, 0 to 100), maps findings to six compliance frameworks, identifies cyber insurance denial triggers, and anchors every result on Base L2 Ethereum for tamper-proof verification. With 36 MCP tools, Google A2A protocol support, and a ChatGPT custom GPT featuring 12 actions across 6 scanning modes, the agent integrates natively into any AI workflow.
What the Agent Autonomously Delivers
- 100-tool external attack surface scan in under 60 seconds
- Cyber Defense Score: letter grade (A-F) + numeric (0-100)
- Autonomous mapping to NIST CSF 2.0, CIS, SOC 2, PCI-DSS, FTC Safeguards, and NIST 800-171
- Cyber insurance readiness assessment with denial trigger identification
- Blockchain-verified scoring anchored on Base L2 Ethereum
- 36 native MCP tools for Claude, Cursor, and AI assistant integration
- ChatGPT custom GPT with 12 actions and 6 scanning modes
- Public trust pages for transparent security posture sharing
Key Features
Six core agentic capabilities engineered to autonomously assess, score, and secure any organization's external attack surface — from instant scanning to blockchain-verified trust.
100-Tool Autonomous Security Scan
The agentic platform autonomously executes a comprehensive 100-tool external attack surface analysis in under 60 seconds — scanning DNS records, SSL configurations, open ports, email security, HTTP headers, and dozens more vectors without any manual intervention or configuration required.
Multi-Framework Compliance Mapping
Every scan result is autonomously mapped across six major compliance frameworks — NIST CSF 2.0, CIS Controls, SOC 2, PCI-DSS, FTC Safeguards Rule, and NIST 800-171 — giving organizations a unified compliance posture view without engaging separate consultants for each framework.
Cyber Insurance Readiness Engine
The agent autonomously identifies the exact denial triggers that cause 41% of cyber insurance applications to be rejected — missing MFA, absent DMARC, open RDP ports, no EDR solution — then generates specific remediation steps and broker-ready evidence packages to secure coverage at lower premiums.
Blockchain-Verified Scoring
Every Cyber Defense Score — a letter grade (A through F) plus a numeric score (0-100) — is cryptographically anchored on Base L2 Ethereum. These immutable, tamper-proof records can be independently verified by anyone, providing trustless proof of an organization's security posture at any point in time.
Agentic AI Integration
A fully agentic architecture with 36 native MCP tools that allow Claude, Cursor, and other AI assistants to autonomously query and act on security data. Includes Google A2A protocol support, a ChatGPT custom GPT with 12 actions and 6 scanning modes, and JSON-LD dual-format output for seamless machine consumption.
Public Trust Pages
Shareable, publicly accessible security posture pages hosted at trust.cyberdefenseagent.ai — enabling organizations to transparently demonstrate their Cyber Defense Score, methodology, and real-time security status to clients, partners, insurers, and regulators without exposing sensitive infrastructure details.
Measured Impact
The Cyber Defense Agent delivers measurable operational advantages — replacing weeks-long assessments and five-figure consulting engagements with autonomous, agentic intelligence available in seconds.
60s
Full Security Assessment
A comprehensive 100-tool external security assessment completes autonomously in under 60 seconds — replacing traditional penetration tests and vulnerability assessments that take 4 to 8 weeks and require scheduling, scoping, and manual analyst review.
36
Native MCP Tools
Thirty-six purpose-built MCP tools enable any AI assistant — Claude, Cursor, ChatGPT, or custom agents — to autonomously query security scores, run scans, pull compliance data, and generate reports through natural language without human intermediation.
90%
Cost Reduction
Delivers enterprise-grade cybersecurity assessment and compliance mapping at a fraction of the cost — replacing traditional alternatives that range from $7,000 for basic penetration tests to $80,000+ for comprehensive compliance audits.
Why This Matters
The Cyber Defense Agent demonstrates Sigma Agents' ability to build complex, multi-layered agentic infrastructure that operates autonomously at national scale. This is not a dashboard or a static report — it is a fully autonomous cybersecurity platform that scans, scores, maps compliance, verifies on-chain, and integrates with AI ecosystems through MCP tools and agent-to-agent protocols.
As the sister product to HIPAA Agent, Cyber Defense Agent extends Sentinel Health Compliance's portfolio from regulatory compliance into active cybersecurity posture management. Together, they represent the kind of agentic platform ecosystem that Sigma Agents specializes in building — purpose-built AI systems that combine blockchain verification, multi-protocol AI integration, and autonomous decision-making to solve real business problems at scale.
What This Demonstrates
- Ability to build complex agentic cybersecurity infrastructure
- National-scale B2B SaaS platform architecture and deployment
- Blockchain + AI protocol integration (Base L2, MCP, A2A)
- Autonomous scanning and scoring without human intervention
- Multi-framework compliance mapping across six industry standards
- Complements HIPAA Agent as a sister agentic product for Sentinel Health
