Autonomous Endpoint Security

SYNTEX.

Reinforcement learning that detects, decides, and acts. Not signatures. Not rules. Not an LLM wrapper. An intelligence engine that gets stronger with every threat it encounters.

AI-Powered Threats Are Already Here
Deepfake attacks, prompt injection, model poisoning, autonomous agent abuse. Nemesis generates them. Guardian stops them. Nobody else trains against threats that don't exist yet.

AI Threat Intelligence

Nemesis

The adversarial intelligence engine that generates attack vectors no signature database contains. Some evolve known techniques into unexplored territory. Others are genuinely new — no MITRE mapping, no CVE, no existing detection rules. Both end up in Guardian before attackers find them first.

    The Industry Problem

    Traditional EDR, SIEM, and SOAR Can't Stop What's Coming

    Signature-based endpoint protection, static SIEM rules, manual SOAR playbooks, and periodic vulnerability scans were built for yesterday's threats. Attacks evolve hourly. Your defenses update quarterly. If you're lucky.

    Traditional EDR
    2010s
    • ✕ Signature-based detection only
    • ✕ Human responds to every alert
    • ✕ Vendor updates lag days to weeks
    • ✕ Capability frozen at deployment
    DETECTION TRAJECTORY
    Flat and static forever
    "AI Security"
    2020s
    • ~ LLM pattern analysis
    • ~ Better alerts, still needs humans
    • ~ Vendor retrains model (still lag)
    • ~ Capability frozen between updates
    DETECTION TRAJECTORY
    Jumps at vendor cadence only

    • ✓ Reinforcement learning from outcomes
    • ✓ Decides and responds autonomously, analysts handle exceptions
    • ✓ Vendor updates plus continuous on-network learning

    Low High Time → Threats Traditional SYNTEX

    SYNTEX is the only platform whose defense is ahead of the threat curve. Trained against attacks that haven't happened yet.

    AI-Powered Threat Intelligence

    Advanced Threat Protection That Learns From Every Attack

    Your defense is trained against thousands of AI-generated attack patterns built on MITRE ATT&CK® foundations and extended with SYNTEX's own SYN-coded threat taxonomy, including threats that haven't been seen in the wild yet but your network is already prepared for.

    Nemesis
    Adversarial Threat Engine
    • 58,000+ AI-generated attack patterns covering ransomware, deepfake, credential theft, supply chain, C2, and social engineering
    • Built on MITRE ATT&CK® and extended with SYN-coded taxonomy
    • Generates threats that don't exist in any public signature database
    • Contained in SYNTEX's lab with zero containment breaches
    CO-EVOLVE
    Guardian AI
    Reinforcement Learning Defense
    • Every autonomous decision logged with Q-values, confidence score, and MITRE tactic mapping
    • Four actions available: block, quarantine, monitor, allow — each with its own Q-value
    • HMAC-signed decision records — tamper-evident audit trail by design
    • Every decision passes 3-check ethics gate before execution
    Automated Incident Response

    How SYNTEX Detects, Decides, and Responds

    Other platforms reduce mean time to detect. SYNTEX reduces mean time to respond. Endpoint detection, threat analysis, autonomous decision, and incident response in one continuous loop.

    Every Decision Logged With Full Reasoning

    Guardian doesn't just block threats. It shows you exactly WHY. Every autonomous decision includes Q-values across all four actions, confidence scores, MITRE tactic mapping, and a human-readable explanation. Your compliance team gets a complete audit trail. Your SOC gets actionable context.

    EU AI Act Article 12 and Article 14 compliant by architecture.

    Your Analysts Become Threat Hunters. Not Alert Processors.

    Guardian handles the volume. High-confidence threats blocked autonomously. Quarantine isolates suspicious activity for review. Monitor watches low-confidence signals. Allow closes out benign events. Your team focuses only on the edge cases that need human judgment.

    BLOCKconfirmed threat
    High confidence, high severity — stopped before execution.
    QUARANTINEisolate for review
    Suspicious activity separated from the running system, held for analyst review.
    MONITORwatch signal
    Low-confidence signal — logged, watched, escalated if pattern repeats.
    ALLOWbenign event
    Ruled benign by the model — still logged for the audit trail.
    Every decision across all four actions is logged with Q-values, confidence, MITRE tactic, and HMAC signature.
    3-Check Ethics Gate
    Every autonomous action passes three independent checks before execution: ethics gate, guardian ethics, and symbiotic safety. If any check fails, the action is blocked. Not a policy doc. Enforced in code.
    24-Hour Pending Window
    High-severity actions enter a pending state. Your team has 24 hours to review, approve, or override before execution. AI recommends. Humans decide. No CrowdStrike-class failures.
    Reinforcement Learning
    Not static signatures. Guardian uses Q-learning trained against Nemesis's continuously generated adversarial patterns. Every decision updates the model. Detection accuracy improves the longer it runs on your network.
    HMAC-Verified Integrity
    Every decision record is cryptographically signed. If an attacker tampers with logs, the HMAC verification fails. Your audit trail is tamper-evident by design.
    AI Safety & Compliance Readiness

    AI Governance Built Into Every Autonomous Decision

    Guardian AI makes real security decisions: block, quarantine, monitor, or allow. Every one passes through structural safety constraints before execution, architected for SOC 2, HIPAA, ISO 27001, and EU AI Act readiness from the ground up.

    July 2025

    An AI agent deleted a production database, then lied about recoverability.

    Replit's AI agent wiped 1,200+ executive records. Violated explicit instructions. Fabricated status reports.

    Guardian can't do this

    Destructive operations don't exist in Guardian's action space. No code path to delete data, modify system files, or execute commands outside its defined scope.

    2025

    A compromised AI agent cascaded false approvals. $3.2M in fraudulent orders.

    One rogue agent poisoned 87% of downstream decisions within 4 hours in a multi-agent system.

    Guardian can't do this

    Each Guardian module has its own bounded observation and action space. No module can override another's decisions. Cascading approval is architecturally impossible.

    December 2025

    OWASP released a Top 10 for Agentic AI. The industry acknowledged autonomous AI needs its own threat model.

    Top risks: agent goal hijacking, tool misuse, privilege escalation, cascading failures, rogue agents, supply chain attacks.

    Guardian addresses the full OWASP Agentic Top 10

    Goal hijacking: bounded action spaces. Tool misuse: zero dependencies. Privilege escalation: no root, user-space only. Cascading failures: module isolation.

    Ongoing 2025-2026

    AI agents gradually favor efficiency over safety. Executing actions never authorized by humans.

    The International AI Safety Report 2026 documented policy drift: autonomous systems optimizing metrics at the expense of safety.

    Guardian can't do this

    Guardian's ethical constraints are not learned parameters. They cannot drift because they are not part of the optimization objective. The boundaries are walls, not furniture the model can rearrange.

    What you're actually replacing

    Most small and midsize organizations run four separate endpoint security tools from four separate vendors with four separate contracts. SYNTEX replaces the endpoint security stack in one product. Your M365 or Google Workspace security subscription covers cloud tenant threats.

    Capability Typical separate vendor SYNTEX
    Endpoint detection & response (EDR) CrowdStrike, SentinelOne Included
    Security event correlation (SIEM) Splunk / Cisco, Microsoft Sentinel Included
    Automated response (SOAR) Palo Alto XSOAR, Swimlane Included
    Vulnerability scanning Tenable, Qualys Included
    Managed detection & response (MDR) Separate contract, per-hour IR retainer Included (L4 autonomous + human)
    Total contracts to buy 4–5 vendors 1 — $199/endpoint/mo

    We don't publish competitor pricing on our site — vendors change packaging constantly and most enterprise deals are negotiated. Check current pricing directly at each vendor's site. The real cost of running four separate contracts is the integration, the renewals, and the human hours spent stitching them together.

    Built for 1–500 endpoint organizations with primarily endpoint-based telemetry. Pairs with M365 / Google Workspace native security for cloud tenant coverage. For 1,000+ endpoint enterprises with custom log sources and multi-cloud infrastructure, talk to us about our enterprise roadmap.
