Security for the age of AI agents.
AI that acts, not just answers, is the fastest-growing attack surface in the enterprise. Zero Day Security helps you see it, govern it, and put controls in place that actually stop attacks, not just scan for them.
Agentic AI breaks the assumptions your security was built on.
Agents read untrusted content, hold their own access, and act on their own. The controls most organizations built for software and for people were not designed for that. Three shifts a security program has to absorb:
A new attack surface
Prompt injection, tool misuse, agent-to-agent cascades and memory leakage are live techniques, not lab curiosities. They target the reasoning layer, which traditional controls never inspected.
Posture is not protection
Discovering and scanning your AI shows what you have and where it is weak, but it stops nothing at runtime, and the hardest gaps are architecture, not something a product fixes. Visibility comes first; on its own it is not a control.
It is a board responsibility
Oversight of material AI and model risk sits with the board. Regulators increasingly expect that AI is inventoried, governed and evidenced, even where no single rule names it yet.
From a first gap assessment to a fully run security function.
Three jobs, nine ways we help. Start with the free assessment; everything else is delivered as an engagement or a retainer.
Understand where you stand and what it exposes you to.
AI Security Gap Assessment →Board-ready map of your AI risk. Free. Security Advisory & Assurance →Senior judgment, plus independent assurance. M&A Security Due Diligence →Surface the security risk before close.Surface the weaknesses, then close them.
AI Reviews & Red Teaming →Adversarial testing of your AI. Penetration Testing →What a real attacker could reach. Incident Response →Contain it now, prevent the next one.Operate securely, and prove it.
vCISO / Fractional CISO →Senior security leadership on retainer. SOC 2 & Compliance Readiness →Get audit-ready, no busywork. Agentic-AI Vendor Selection →Choose the right platform, proven.Four kinds of organization, one job: adopt AI without losing control of it.
Banks, financial institutions and enterprises
You are rolling out copilots, automation and agents across the business, and the board is asking who owns the risk. We give you a defensible answer: what AI is in use, where it is exposed, and a sequenced plan to govern and control it.
How we help
- Board-ready AI gap assessment and roadmap
- AI governance, inventory and guardrails
- vCISO leadership and board reporting
Teams building AI into regulated industries
You are moving fast into legal, healthcare or finance, and security is now a deal-blocker on every enterprise contract. We act as your security function: review the product, harden the AI, and get you through SOC 2 without slowing the roadmap.
How we help
- AI security reviews and red teaming
- Security-expert retainer / vCISO
- SOC 2 and compliance readiness
Security and AI diligence for the deal
You need to know exactly what's in the deal before you sign, and what it will take to fix after. We run security and AI-strategy due diligence across the portfolio, translate risk into dollars and timelines, and stay on as the post-close security partner.
How we help
- Pre-deal security & AI-strategy due diligence
- Risk quantified for the investment thesis
- Post-close remediation and 100-day plan
Fractional security leadership for the firm
Your firm holds some of the most sensitive data there is, adopts AI tools quickly, and rarely has a security leader in-house. We are that leader on a fractional basis: practical governance, client-security questionnaires handled, and AI tools adopted safely.
How we help
- Fractional CISO / security leadership
- Safe adoption of AI and legal-tech tools
- Client security questionnaires and assurance
Where does your organization stand on AI security?
Answer a few questions and a seven-domain self-check, and download a board-ready gap assessment and roadmap in about three minutes. No login. Grounded in public security standards: OWASP, MITRE ATLAS, NIST AI RMF and ISO/IEC 42001.
- A live gap heatmap across seven control domains
- A risk tier and AI-security maturity level
- A sequenced roadmap, downloadable as PDF and Word
- Tailored to your market: US, Canada, EU or global
Diagnose first. Then govern, build and assure.
The free assessment diagnoses for everyone. The engagement is where we prescribe and deliver. We sequence the work so the controls that cut the most risk land first.
See the whole estate
Inventory every AI system and agent, rate the risk, and surface the gaps against a seven-domain control framework. You cannot protect what you cannot see.
Put someone in charge
Name an accountable owner, set policy and guardrails, and get a plain-language AI-risk report running to the board on a regular cadence.
Stand up the controls
Scoped identities, runtime guardrails, detection and rehearsed containment. We build the controls that stop attacks, and prove they work in your systems.
Keep it audit-ready
Routine red teaming, governed metrics and continuous assurance, so you can evidence your AI-risk posture to a board, a customer or a regulator on demand.
Frequently asked questions
What is agentic AI security?
Agentic AI security is the practice of protecting AI systems that act, not just answer: agents that call tools, move data, hold their own access and carry out tasks. It covers attack paths like prompt injection, tool misuse, agent-memory leakage and multi-agent cascades, which traditional application security was never designed to catch.
How is securing AI agents different from normal application security?
Agents read untrusted content, choose which actions to take, and keep their own memory, so the assumptions classic controls relied on no longer hold. You have to watch how an agent behaves at runtime, check every action before it runs, and treat each agent as its own identity with least-privilege access, not just secure the code around it.
What does the free AI security assessment include?
It maps your posture across seven control domains, computes a risk tier and an AI-security maturity level, and produces a board-ready gap assessment and roadmap you can download. It takes about three minutes, needs no login, and every finding is grounded in public frameworks (OWASP, MITRE ATLAS, NIST AI RMF, ISO/IEC 42001) rather than generated by a model.
Do you sell security products?
No. We are vendor-neutral and not resellers. When a tool is the right answer we will say so, and when a platform decision is needed we evaluate the options against a defensible framework and prove it in a sandbox before you sign anything.
What is a vCISO (fractional CISO)?
A vCISO is a senior security leader who owns your security program on a part-time, retained basis: strategy, governance, board reporting and day-to-day security decisions, without the cost of a full-time executive. It suits organizations that need senior security ownership but not a full-time hire.
Which organizations do you work with?
Four kinds of organization adopting AI: enterprises and financial institutions, AI-native startups moving into regulated industries, private equity firms doing security and AI diligence on deals, and law firms that need fractional security leadership.
