Security Policy

import "github.com/declaw-ai/declaw-go"

A SecurityPolicy is passed to Create() via the WithSecurity option. It composes PII detection, injection defense, toxicity / code-security / invisible-text scanners, network policy, transformation rules, audit logging, and environment variable security into a single struct.

SecurityPolicy

policy := declaw.SecurityPolicy{
    PII: &declaw.PIIConfig{
        Enabled: true,
        Types:   []declaw.PIIType{declaw.PIIEmail, declaw.PIICreditCard},
        Action:  declaw.RedactionActionRedact,
    },
    InjectionDefense: &declaw.InjectionDefenseConfig{
        Enabled: true,
        Action:  declaw.InjectionActionBlock,
    },
    Audit: &declaw.AuditConfig{Enabled: true},
}

sbx, err := declaw.Create(ctx,
    declaw.WithSecurity(policy),
)

Field	Type	Default	Description
`Enabled`	`bool`	`false`	Whether invisible-text scanning is active
`DetectZeroWidth`	`bool`	`false`	Detect zero-width characters

CustomPolicyConfig

Attach OPA/Rego policy — a built-in governance pack via PolicyRef, or your own rules via InlineRego/InlineModules. Custom rules are evaluated at the enforcement layer alongside the platform defaults and can only tighten policy, never relax it.

// Reference a built-in governance pack
custom := &declaw.CustomPolicyConfig{
    Enabled:   true,
    PolicyRef: "owasp-llm-top10@v1",
}

// Or supply your own Rego
custom := &declaw.CustomPolicyConfig{
    Enabled: true,
    InlineRego: `
        deny_command contains msg if {
            input.action.command in {"rm", "dd"}
            msg := "dangerous command blocked"
        }
    `,
}

Field	Type	Default	Description
`Enabled`	`bool`	`false`	Whether custom policy evaluation is active
`InlineRego`	`string`	`""`	A single Rego module string appended to platform defaults
`InlineModules`	`[]string`	`nil`	Independent Rego module strings, each its own `package`
`PolicyRef`	`string`	`""`	Reference a bundle by `name@version`, `sha256:<hex>`, or `blob:<key>`
`DefaultDeny`	`bool`	`false`	Fail-closed: when `true`, an evaluator error denies the action

See Custom Policy and Governance Packs for the full guides.

ContentGateConfig

Run the content.scan OPA gate (e.g. an LLM model allowlist / cross-signal rules) on the listed domains. Opts a sandbox into content-gate enforcement without requiring an ML scanner to be enabled.

content := &declaw.ContentGateConfig{
    Enabled: true,
    Domains: []string{"api.openai.com", "api.anthropic.com"},
}

Field	Type	Default	Description
`Enabled`	`bool`	`false`	Whether the content gate is active
`Domains`	`[]string`	`nil`	Opt-in destination hosts to intercept; empty intercepts none

See Custom Policy for details.

NetworkPolicy

Network allowlist and denylist for outbound traffic from the sandbox.

network := &declaw.NetworkPolicy{
    AllowOut: []string{"pypi.org", "*.github.com"},
    DenyOut:  []string{"0.0.0.0/0"}, // or use declaw.AllTraffic for wildcard "*"
}

Field	Type	Description
`AllowOut`	`[]string`	Destinations to allow (IPs, CIDRs, domains)
`DenyOut`	`[]string`	Destinations to deny (IPs, CIDRs)

TransformationRule

Regex-based text transformation applied to outbound request bodies, inbound response bodies, or both.

rule := declaw.TransformationRule{
    Match:     `Bearer [A-Za-z0-9\-_\.]+`,
    Replace:   "Bearer [REDACTED]",
    Direction: declaw.TransformOut,
}

Field	Type	Description
`Match`	`string`	Regular expression pattern
`Replace`	`string`	Replacement string
`Direction`	`TransformDirection`	`"in"`, `"out"`, or `"both"`

AuditConfig

Toggle audit logging for sandbox activity.

audit := &declaw.AuditConfig{
    Enabled:             true,
    RedactSensitiveData: true,
}

EnvSecurityConfig

Control how environment variable values are masked in audit logs.

envSec := &declaw.EnvSecurityConfig{
    MaskPatterns: []string{"*_KEY", "*_SECRET", "*_TOKEN"},
    SensitiveVars: []declaw.SecureEnvVar{
        {Name: "OPENAI_API_KEY", Value: "sk-..."},
    },
}
