Emergency Control

Agent Kill Switch

Instantly terminate any AI agent at any scope level. The kill switch provides immediate, granular control when an agent exhibits dangerous behavior or exceeds its authority.

Scope Hierarchy

Organization
Team / Department
Agent Fleet
Individual Agent

Parent kill inherits to all children. Organization kill disables everything.

Activation Triggers

Budget Exceeded

Agent spending surpasses allocated token or cost budget thresholds.

Security Violation

Agent attempts unauthorized actions, data exfiltration, or privilege escalation.

Anomalous Behavior

Behavioral drift detected via z-score or IQR analysis against established baselines.

Manual Override

Human operator manually terminates agent operation for any operational reason.

Tool Security

MCP Firewall

Every tool call from every agent passes through the MCP Firewall. 24 injection patterns, whitelist validation, and parameter sanitization ensure agents only use tools safely.

Tool Name Validation

Whitelist-based tool access control. Agents can only invoke explicitly approved tools matching their guardrail profile.

38 Injection Patterns

Comprehensive regex-based detection of SSRF, command injection, path traversal, SQL injection, and template injection in tool parameters.

Parameter Sanitization

Input validation and sanitization for all tool call parameters. Prevents encoded payloads, Unicode tricks, and nested injection attacks.

Call Count Limits

Per-agent, per-tool rate limiting to prevent runaway tool invocation loops. Configurable burst and sustained rate thresholds.

Behavioral Analytics

VibeGuard Monitoring

Continuous behavioral analysis of every AI agent using statistical anomaly detection. VibeGuard establishes behavioral baselines and flags deviations before they become incidents.

Detection Methods

Z-Score

Measures how many standard deviations a metric is from the mean. Triggers alert at configurable sigma thresholds (default: 2.5 sigma).

IQR

Interquartile Range analysis robust against outliers. Identifies anomalies beyond Q1 - 1.5*IQR or Q3 + 1.5*IQR boundaries.

Monitored Metrics

Response Latency

Detects sudden slowdowns indicating resource contention or stuck loops

Token Velocity

Monitors tokens-per-minute for anomalous bursts or silent periods

Tool Call Frequency

Tracks tool invocation patterns against established baselines

Error Rate

Flags elevated error rates that may indicate exploitation attempts

Output Entropy

Measures response randomness to detect hallucination spirals

Scope Drift

Identifies when agents operate outside their designated task boundaries

Trust Zones

Progressive capability elevation based on agent trust scores. Higher trust unlocks more autonomy. Lower trust restricts to safe operations.

Green Zone

Score: 80-100
  • Full tool access per guardrail profile
  • Autonomous multi-step operations
  • Direct external API calls
  • Data read/write access
  • Inter-agent communication

Yellow Zone

Score: 50-79
  • Restricted tool access (read-only)
  • Human-in-the-loop for writes
  • External calls require approval
  • Data read access only
  • Monitored inter-agent communication

Red Zone

Score: 0-49
  • All tools disabled
  • Read-only mode enforced
  • No external API access
  • Quarantined from other agents
  • Mandatory security review required
Cryptographic Security

Inter-Agent HMAC Security

Every message between agents is cryptographically signed and verified. No impersonation. No tampering. No replay attacks.

HMAC-SHA256 Signing

Every inter-agent message includes an HMAC-SHA256 signature computed over the full message payload. Receiving agents verify signatures before processing.

Replay Prevention

Messages include a cryptographic nonce and timestamp. Agents reject messages outside a configurable time window and maintain a nonce cache to prevent replay.

Agent Identity Verification

Each agent has a unique key pair for signing. Agent identity is verified against the AEGIS agent registry before communication is established.

Agent A
Signs message
HMAC + Nonce + Timestamp
Agent B
Verifies signature

OWASP Agentic Top 10

Colossal provides coverage for 9 out of 10 OWASP Agentic Security Items, with the remaining item under active development.

IDColossal CoverageStatus
ASI-01
Agent Goal HijackEvery request is inspected for instructions that redirect an agent away from its purpose, and a guardrail profile sets the boundaries it must stay inside.
Covered
ASI-02
Tool Misuse & ExploitationTool calls are authorised per agent and refused outside its scope. Tool definitions are pinned on first sight, so a changed description is reported before it is followed.
Covered
ASI-03
Agent Identity & Privilege AbuseEach agent carries its own short-lived workload identity, scoped to a trust zone, and the credential expires with the identity rather than outliving it.
Covered
ASI-04
Agentic Supply Chain CompromiseAn approved bill of materials is pinned per repository and every later scan is compared against it, so a dependency that moves under an unchanged name is reported. Publisher signing is not part of this.
Partial
ASI-05
Unexpected Code ExecutionDeployments that expose code-execution tools are identified before they ship, and calls to those tools are refused outside an agent's authorised scope. The platform governs the agent's traffic; it does not execute or sandbox your code.
Partial
ASI-06
Memory & Context PoisoningRetrieved knowledge is checked for integrity at the moment it is used, and content that was altered after indexing, or that belongs to another tenant, is refused rather than answered from.
Covered
ASI-07
Insecure Inter-Agent CommunicationMessages between agents are signed and verified, and a replayed message is rejected.
Covered
ASI-08
Cascading Agent FailuresKill switches, rate and spend limits, and a machine-speed guard that runs on a schedule rather than on request. A payload seen at a second agent inside the window is correlated and raised.
Covered
ASI-09
Human-Agent Trust ExploitationHigh-impact actions can require a person before they proceed, responses are validated before they reach the user, and planted canary values reveal an answer that should never have been produced.
Covered
ASI-10
Rogue AgentsAgents are discovered from real traffic and enrolled, and unregistered traffic can be refused. The gate ships in monitor so nothing breaks on the day it is switched on; enforcing it is the customer's decision.

Discovery Engine

Shadow AI Discovery

Unsanctioned AI usage is a growing shadow IT risk. Colossal's Shadow AI Discovery engine identifies unauthorized AI model deployments, API calls, and integrations across your environment.

  • Pattern-based detection of known AI provider API signatures
  • Model fingerprinting to identify specific LLMs in use
  • DNS and network traffic analysis for AI service endpoints
  • OAuth scope scanning for third-party AI integrations
  • SaaS application inventory for embedded AI features
  • Automated policy enforcement for discovered AI usage

Discovery Pipeline

Scan

Monitor network traffic, DNS logs, and OAuth grants for AI-related signatures

Identify

Match discovered endpoints against a database of 33+ known AI provider patterns

Fingerprint

Determine specific model versions through response analysis and behavioral profiling

Classify

Categorize discovered AI as sanctioned, unsanctioned, or unknown and assess risk level
