How KeyValue led Cyber Sierra’s AI transformation, from first prompt to AI analysts in production

Compliance Agentic AI Data & search Cloud

KeyValue turned an established compliance platform into an AI-first product, with AI analysts that audit evidence, answer security questionnaires and search every record — built to the standard auditors and regulators expect.

Client requirement

Make compliance work AI-first, without lowering the bar

Founded in Singapore in 2020, Cyber Sierra helps banks, insurers and other regulated organisations prove they follow security and compliance rules — known as governance, risk and compliance (GRC). Every rule (a “control”) must be backed by proof (the “evidence”), and someone has to check it. The goal was to have AI analysts do that checking, with people approving every decision.

That meant solving the problems every compliance team knows

Weeks of manual review

A single ISO 27001 certification covers 93 controls, each with documents someone must read and sign off by hand.

Repeated questionnaire work

Enterprise buyers send hundreds of questions whose answers already exist in approved evidence.

Samples, not coverage

Teams review a sample, and gaps surface at the next audit — after the certificate is already signed.

Our role

An AI engineering team, side by side with the product

KeyValue’s AI engineering team works alongside Cyber Sierra’s developers on the platform’s AI features, from research and prototypes through to production. A new AI agent typically reaches its first release about six weeks after the first commit.

    AI analysts across the platform

“The hard part was never getting a model to answer. It was getting one to abstain, to repeat itself exactly, to cite only what it used, and to stop safely when something is missing.”KeyValue AI engineering team
What we built

Four AI capabilities, one shared document library

Every capability draws from the compliance team’s existing documents, ensuring answers are backed by approved evidence and expired documents are excluded.

Audit

Evidence Auditor

Reviews the evidence behind each control and explains whether it meets the requirement — with the justification, the gap, and a recommendation.

Answer

Due Diligence Analyst

Drafts answers to security questionnaires from approved evidence, with a confidence score and sources on every answer — returned in the customer’s original file.

Search

Semantic Search

Finds information across compliance records using plain language — combining keyword precision with semantic understanding of the compliance domain.

Insight

Dashboard Builder

Turns a plain-English question into a chart over the customer’s own compliance data — and says so when the data can’t support a metric.

The AI reads and reasons, a person makes the call, and every step is recorded.

Flags what it can’t support

For a person to review.

Challenges we surpassed

Making AI decisions hold up in an audit

The hard part is making AI decisions consistent, explainable and safe to rely on.

Consistent, defensible decisions

AI interprets the evidence; clear rules make the final call, so similar evidence gets similar answers — with a justification an auditor can check.

No two audits look the same

A modular design gives each type of audit the right checks, and new capabilities can be added without a rebuild.

Real contradictions, not false alarms

Genuine conflicts between documents are separated from simple differences in wording, and uncertain cases go to a person.

Secure, offline deployments

The platform, AI included, can run in locked-down environments with no internet access — shipped behind a single CLI for a non-engineer to run.
