AI introduces a new attack surface — prompt injection, data leakage, agent overreach, vendor risk. Your fractional Chief AI Officer designs security in from day one, grounded in OWASP, NIST, and MITRE — and gives you the review-ready evidence you can hand to your board.
AI risk is probabilistic, leaky, and accessible. Anyone with a text input can probe the model. PII can leak via prompts. Agents can overreach when tool access is too broad. Vendor data and retention settings can differ by product tier. And hallucinations get committed by humans assuming the AI was right. Traditional perimeter thinking doesn’t meet this risk — the threat enters through the same interface your customers use.
The SMB exposure
For SMBs the exposure is asymmetric: the same regulatory expectations as enterprise, a fraction of the security headcount. The answer is not bolting on security after launch. The answer is designing security in from day one and using recognized standards as the evidence model.
Defense in depth
Five layers we defend on every AI workflow.
Defense in depth reduces the chance that one control failure becomes a system-wide failure. We design workflows so sensitive data, model behavior, tool access, and operational response each have their own control layer.
Layer 01
What enters the system
Data layer
Protects against
PII leakage, secret exposure, prompt-laundered data exfiltration. The first opportunity for sensitive data to leave your boundary is the moment a user types it into a prompt — that’s where you stop it.
Controls in practice
Pre-send PII redaction at the gateway
Secret scanning before any prompt leaves your network
Encryption in transit and at rest, end-to-end
Minimum-necessary data in every prompt
Data classification before processing
Layer 02
Provider selection and configuration
Model layer
Protects against
Vendor data retention abuse, training on your data, residency violations. The provider you choose — and how it’s configured — determines who else can ever see, learn from, or be subpoenaed for your data.
Controls in practice
Commercial or enterprise terms for business data
Retention controls configured where available
BAAs for applicable healthcare workloads, DPAs where needed
BYO-key / customer-managed keys where available
Provider risk register reviewed quarterly
Layer 03
Guardrails in the product
Application layer
Protects against
Prompt injection, jailbreaks, sensitive output leakage, unbounded cost. The application is where adversaries meet your model — and where most real-world attacks land. This is your front line.
Controls in practice
Parameterized prompt templates — user input is data, not code
Input sanitization on every untrusted source
Output redaction for PII, secrets, and keys
Jailbreak classifiers on inbound and outbound
Per-user rate limits and consumption caps
Layer 04
When AI takes actions
Agent layer
Protects against
Excessive agency, runaway tool calls, unintended state changes. The moment the model can act on the world, the blast radius of a single bad decision multiplies — this layer keeps that radius bounded.
Controls in practice
Capability allowlists (not denylists)
Sandboxed tool execution — one workflow, one scope
Human-in-the-loop on consequential actions
Per-action audit trail with reviewer identity
Kill switches per workflow, drilled quarterly
Layer 05
Visibility and response
Operational layer
Protects against
Silent failures, undetected drift, slow incident response. The controls above only hold if you can see them holding — this layer keeps the lights on and the system honest over time.
Controls in practice
Tamper-evident audit logging on every decision
Anomaly and budget alerting in real time
Quarterly red-team exercises against OWASP + MITRE ATLAS
Incident response playbook with named owners
Continuous evaluations against your KPIs
Five layers, defense in depth. One control layer failing should not mean the whole workflow fails.
Frameworks
We don’t invent the standards. We operate from them.
Every deployment is anchored to industry frameworks your auditors, insurers, and enterprise customers already recognize. That’s how a security decision becomes a defensible one.
OWASP Top 10 for LLM Applications
2025 edition
A widely used industry checklist for LLM application threats: prompt injection, sensitive information disclosure, supply chain risk, excessive agency, system prompt leakage, vector and embedding weaknesses, misinformation, unbounded consumption, and more. Maintained by a global community of security practitioners.
How we use it
Every deployment is mapped against the Top 10 before launch. Each item is either mitigated with a documented control or formally accepted with an owner and review date.
NIST AI Risk Management Framework
Govern · Map · Measure · Manage
A voluntary U.S. government framework for managing AI risks and improving trustworthy AI practices. It provides a structured way to think about AI risk across governance, mapping, measurement, and management activities.
How we use it
We translate NIST AI RMF into your environment: a one-page AI policy, a threat map, a KPI dashboard, and an incident playbook — sized for an SMB, not a Fortune 500.
MITRE ATLAS
Adversarial Threat Landscape for AI Systems
The MITRE-maintained catalog of known AI attack tactics, techniques, and case studies. The ATT&CK matrix, but for adversarial machine learning — prompt injection, model evasion, training-data poisoning, model theft, and more.
How we use it
Our quarterly red-team exercises probe your deployments against ATLAS techniques. Findings become prioritized remediation items with owners and target dates.
Vendor enterprise privacy standards
OpenAI Business · Anthropic Enterprise · Vertex · Azure OpenAI
Enterprise AI providers publish product-specific privacy, security, and compliance terms. Depending on the provider and plan, those terms may include training opt-outs, configurable retention, BAA availability, regional controls, encryption options, SOC 2 reports, or ISO 27001 certificates.
How we use it
We compare vendors against your regulatory profile, configure the strongest applicable settings available on the chosen tier, and keep a living vendor risk register so material policy changes are reviewed.
Anthropic RSP + OpenAI Preparedness
Frontier safety frameworks
Responsible Scaling Policies and Preparedness frameworks — published by model providers themselves — describe internal evaluation and capability-threshold approaches for powerful systems. SMB deployments can borrow the pattern: evaluate before launch, stage rollout, and define when to pause.
How we use it
When we ship agentic systems, we follow the same internal-evaluation patterns: capability evals, pre-launch red-teaming, staged rollout, and explicit deprecation criteria.
SOC 2 + ISO 27001 alignment
Trust services criteria & ISMS controls
The control families your auditors already know — access management, change management, monitoring, incident response, vendor management — apply directly to AI workloads. Mapping into them keeps your AI evidence inside your existing compliance program, not adjacent to it.
How we use it
We design AI-specific evidence to drop into your existing SOC 2 / ISO 27001 control set: model inventory, prompt change management, output monitoring, vendor reviews.
Guardrails
Six guardrails on protected workflow we ship.
The frameworks tell you what to defend. The guardrails are how we actually defend it — concrete, code-level patterns that ship with protected AI workflows we deploy.
01
Pre-send PII redaction
A pre-flight filter scrubs identifiers before any prompt leaves your network. Names, account numbers, PHI markers, and other classified fields are redacted, replaced with pseudonyms, or blocked entirely.
Pattern
Regex + ML-based detectors running at the gateway, with policy per workflow and per data classification.
Value
Reduces accidental data sharing with model providers when an employee pastes the wrong thing into the wrong window.
02
Prompt template isolation
System prompts and user input are kept structurally separate so user content is less able to rewrite instructions. The implementation avoids relying on a single flattened string and uses explicitly typed roles.
Pattern
Parameterized templates with a strict {user_input} slot, role-aware messages, and escape rules for embedded text.
Value
Reduces prompt-injection risk and makes the interaction easier to inspect in the audit log.
03
Output filtering & redaction
Responses in protected workflows are screened for secrets, keys, PII, and policy-forbidden content before they reach the user, downstream system, or log.
Pattern
Regex sweeps plus a policy classifier, with severity tiers and configurable actions: redact, block, or escalate.
Value
Catches leakage even when input controls missed something — a second line of defense on the way out.
04
Capability allowlists for agents
Agents can only call APIs, tools, files, and resources explicitly granted to them. Everything else is rejected and logged as an anomaly.
Pattern
A broker enforces the allowlist on tool calls; service accounts are workflow-scoped where feasible.
Value
Limits excessive agency by making unauthorized tool use fail closed and appear in logs.
05
Rate limits + budget alerts
Per-user token caps, per-workflow concurrency limits, and hard monthly spend ceilings. Anomalies and budget thresholds wake the right person in real time.
Pattern
Gateway-level throttling with alerts firing at 60% / 80% / 100% of budget, plus rate-of-change detection.
Value
Protects against runaway cost, scripted abuse, and the slow-burn breach that only shows up in next month’s bill.
06
Tamper-evident audit logging
Inputs, outputs, model versions, decisions, and tool calls are recorded where the workflow risk requires it. The log is designed as operating evidence, not a forensic afterthought.
Pattern
Append-only logs with cryptographic chaining, retention policies matched to your regulator, and exportable on demand.
Value
Lets you replay, audit, and prove what happened — to your team, your customers, or your regulators.
