ORCA Opti vs Microsoft Copilot
Copilot makes your team faster. ORCA makes them faster and accountable.
Microsoft Copilot is an excellent assistant. It was built to help your people work, not to prove they worked safely.
ORCA Opti adds the governance, compliance and data-leak protection Copilot was never designed to provide, on the same Microsoft 365 you already trust.
The honest version
This is not Copilot versus ORCA. It is Copilot plus ORCA.
Building on Microsoft 365 was a deliberate security decision, not a default. We run on the same platform as Copilot, and we think Copilot is a genuinely great tool. The gap is not speed. The gap is accountability: who can see what your team sends to AI, whether sensitive data is leaving, and whether you could prove your AI use is safe if a regulator, an auditor or a defence prime asked tomorrow. That gap is exactly what ORCA Opti closes.
Grounded in the field
What teams actually run into with Copilot
These are not reasons to avoid AI, and they are not knocks on Microsoft, who has shipped real controls like Purview and SharePoint Advanced Management to help. They are the predictable challenges of putting powerful AI on top of a real organisation. Each one is a governance gap, and governance is what ORCA Opti is for.
Copilot can only see what your permissions already allow
Copilot inherits each person's existing access, so years of quietly over-shared files suddenly become searchable. In a June 2024 Gartner survey of 132 IT leaders, 40 per cent delayed their Copilot rollout by three months or more over data oversharing, and 64 per cent said governance and security took significant time and resources to manage (Gartner, 2024). Concentric AI's Data Risk Report put roughly 802,000 files per organisation at risk from oversharing (Concentric AI, 2025).
How ORCA Opti helpsORCA Opti works inside your governed Safe Zone, and AI Guardian inspects every prompt in real time, so sensitive information is caught before it surfaces or leaves. You get the assistant without first having to untangle every legacy permission.
AI brings a brand-new class of risk: prompt injection
In 2025, researchers disclosed EchoLeak (CVE-2025-32711), a zero-click flaw that could coax Microsoft 365 Copilot into leaking data from a single crafted email. Microsoft patched it quickly and found no sign it had been exploited, and credit to them for the fast response, but it showed that every AI assistant now faces attacks traditional security tools were never built to catch.
How ORCA Opti helpsThis is exactly why AI needs its own inspection layer. AI Guardian watches every interaction, blocks sensitive data from leaving your environment, and runs on sovereign infrastructure with a complete assurance trail, so your AI is monitored the way the rest of your stack already is.
General-purpose AI can sound confident and still be wrong
Analysts and reviewers have consistently flagged that general AI assistants can hallucinate: meeting and document summaries that miss or invent details, so output cannot be trusted without checking it first. In a compliance setting, an answer you cannot verify is a liability rather than a help.
How ORCA Opti helpsOpti Assist answers from your own documents and the frameworks your industry runs on, with source citations you can trace. Answers are grounded, logged and auditable, the difference between a handy draft and evidence you can stand behind.

Why Microsoft
Why we built ORCA Opti on Microsoft 365
Being Microsoft-native is a deliberate security decision, not a limitation. Three reasons it makes ORCA Opti stronger.
Your identity is your perimeter
You sign in with the Microsoft 365 work account you already have. Single sign-on, multi-factor authentication and your organisation's conditional access policies protect every session. There is no new password to manage and no separate account for IT to govern.
Sovereign by design
ORCA Opti runs on sovereign infrastructure. Your data stays in your Safe Zone, in your region, and is never used to train third-party models. For organisations that need processing inside their own Microsoft 365 or Azure tenancy, that is available on the ORCA-Private tier.
Built on the Microsoft security graph
Because ORCA Opti plugs into Microsoft 365 directly, Opti Cyber gives you a live, continuous view of your Microsoft 365 and cloud security posture. The controls you already trust extend to your AI, rather than sitting beside it.
The difference
Copilot answers. ORCA Opti accounts.
The accountability layer that turns an AI answer into evidence you can stand behind. Four things a productivity assistant was never built to give you.
Source citations on every answer
Opti Assist cites the document behind each answer, so you can trace any response back to where it came from instead of taking it on faith.
Every conversation logged
Every question asked, every answer given and every source referenced is recorded automatically, giving you a complete internal audit trail of how AI is used.
A human stays in the loop
Higher-stakes tasks can require human sign-off before anything goes out, and the approval is recorded, so AI assists your people rather than acting unchecked.
Aligned to ISO/IEC 42001
The international standard for responsible AI management is built in from day one, not bolted on later, so your AI use stands up to auditors, primes and regulators.
