    Meridian Suite by Senticit
    Know where you stand. Know where you're headed.

    Eight products live. Two on the way. One decision framework.

    The Meridian Suite is Senticit's unified platform for AI & IT governance. Radar diagnoses, Atlas authors your policy and Compass attests it, Slant monitors your clinical models, Sentinel oversees the rest of your AI stack, Ledger™ collects the evidence continuously, Pulse reports risk to the board, and Signal measures momentum against reality — with Tether and Marshal arriving to extend the same discipline to autonomous agents. All of it runs on one shared Evidence Room, one identity layer, and one decision framework.

    The Senticit Meridian console — an Intelligence Score of 77 out of 100 for Northwind Health, with all eight instruments listed down the left (Radar, Signal, Slant, Compass, Sentinel, Ledger™, Pulse and Atlas) and a 'How the number is assembled' panel showing that four of them — Radar, Signal, Compass and Sentinel — contribute the score while Slant, Ledger™, Pulse and Atlas contribute evidence

    Why a suite — and not ten point tools

    Every Meridian product is useful on its own. Together, they collapse the seams where AI risk and compliance evidence usually get lost.

    One view of risk

    Ten products, one scoring model and one Evidence Room, so executives get a single reading across compliance, AI governance, policy, momentum, and the agents acting on the organisation's behalf.

    Closed-loop oversight

    Findings from Radar feed the Evidence Room; live signals from Slant and Sentinel trigger alerts; Signal reconciles ambition against actual posture.

    Accreditation-aligned by default

    Every product maps to SOC 2, HIPAA, NIST 800-53, NIST AI RMF, ISO 27001, ISO 42001, and the EU AI Act — no manual control mapping.

    Built on Meridian Suite judgment

    The Meridian Suite encodes the same compliance-led decision framework Senticit uses inside its Meridian Suite engagements.

    Cross-Suite Architecture

    Shared services every product runs on

    Built once, consumed everywhere — the reason Meridian scales as a suite instead of ten disconnected apps.

    Senticit Intelligence Score (SIS)

    A composite board-facing score. Today it is a weighted mean of the four instruments that emit a normalized score; the other products contribute evidence and findings rather than a number.

    Meridian Compass™

    Available today

    AI ethics — define, score and attest the guardrails the rest of the suite runs on.

    The suite's ethics layer. Compass maps your obligations to the frameworks that impose them, scores each proposed AI use against the guardrails, derives the timeline those obligations fall due on, and produces the attestation an auditor will accept. It is one of the four instruments that emit a score into the Senticit Intelligence Score.

    Feature set

    Framework mapping
    • Obligations mapped to the frameworks that impose them
    • Coverage gaps named rather than averaged away
    • SOC 2, HIPAA, NIST AI RMF, ISO 42001 and the EU AI Act
    Obligation timeline
    • What falls due, when, and on whom
    • Derived from the mapping rather than kept in a spreadsheet
    • Disclosure readiness assessed per obligation
    Audit package
    • A single assembled bundle an auditor will accept
    • Evidence pulled from the shared Evidence Room

    Monitor

    Meridian Ledger™

    Available today

    Continuous compliance monitoring — always-on evidence collection and control health.

    Formerly Vigil. Ledger turns audit preparation into a background process: it collects evidence continuously, monitors whether each control is actually working, and assesses continuity so a control that quietly stopped running is visible now rather than at the next audit.

    Feature set

    Evidence collection
    • Always-on rather than a pre-audit sprint
    • Written to the shared Evidence Room
    • Findings carry named owners
    Control monitoring
    • Per-control health, continuously tested
    • Failures surfaced when they happen
    • Mapped to SOC 2, HIPAA, ISO 27001 and NIST 800-53
    Continuity
    • A control that stopped running is a finding, not a silence
    • Gaps in the record reported as gaps
    • Audit-ready packages on demand

    Report

    Meridian Pulse™

    Available today

    Executive risk telemetry — a live, board-ready view of technology and security risk.

    Pulse scores risk across internal environments, third parties and AI systems, aggregates it to the portfolio level, and produces the board summary — replacing a static quarterly deck with evidence of which safeguards are working today. It also reports the basis of its own posture, so a reader can see what the number rests on.

    Feature set

    Risk scoring
    • Scored across internal, third-party and AI systems
    • Aggregated to portfolio level
    • Posture basis reported alongside the score
    Board reporting
    • Board-ready summary generated from live data
    • Replaces the static quarterly deck
    • Escalation paths for what is degrading
    Honesty rules
    • Thin coverage is reported as thin coverage
    • The basis of the posture is stated, not implied
    • Contributes evidence and findings rather than a headline score

    Author

    Meridian Atlas™

    Available today

    AI policy workspace — author, version and operationalize the policies you are judged on.

    Atlas is where AI policies are written, revised with an integer version history, and turned into operational controls with a named owner. It grades how enforceable a policy actually reads, and reports what the latest revision DID — including the case where a policy's score rose while it quietly stopped saying "must".

    Feature set

    Authoring & versioning
    • Integer-versioned drafts and revisions
    • Published, draft and retired states tracked
    • Operational controls and a named owner per policy
    Drafting quality
    • Graded on how enforceable the policy text reads
    • Scope, mandatory language, accountability, cadence, enforcement
    • Deterministic and offline
    Amendment read
    • What the latest revision actually did, per dimension
    • Flags a revision that weakened the guardrail
    • Names the case where the score rose as the policy stopped binding

    Meridian Tether™

    In planning

    Autonomous-agent monitoring — discover every agent, baseline it, catch drift.

    The agent layer's eyes. Most organisations cannot say how many autonomous agents they run or what those agents can touch. Tether discovers every agent it can reach — including shadow agents — baselines how each one behaves, and flags drift against that agent's own history. It observes and proves; it never sits in the execution path.

    Feature set

    Discovery & Registry
    • Auto-surfaces agents, including shadow agents in Zapier, copilots and one-off scripts
    • Owner, purpose and models recorded per agent
    • The tools and data inside each agent's scope
    Behaviour & Drift
    • A behavioural baseline per agent
    • Scope creep and unusual tool use flagged against that agent's own history
    • Failure-spike and anomaly detection
    Observability
    • Action and tool-call detail across a multi-step run
    • Per-agent risk scoring into the Intelligence Score
    • Alerting to the agent's named owner, with evidence attached
    The boundary
    • Monitoring and evidence, not inline enforcement
    • Hands off to an enforcement layer where one exists
    • Never sits in the execution path
    Prove

    Meridian Marshal™

    In planning

    Agent-workflow governance — trace the workflow, approve the risky steps, prove the chain.

    The agent layer's record. When agents chain steps and hand off to one another, there is no account of why the workflow acted. Marshal traces every step, raises a named human approval where risk demands it, and hands auditors the whole chain. Its gates are approval checkpoints: it governs alongside the pipeline and never halts it.

    Feature set

    Lineage & audit
    • A queryable, replayable chain: prompt → tool → data → decision → output → actor
    • An immutable, timestamped record of every step, approval and override
    • Auditor- and customer-shareable trust reports generated from the trail
    Approvals
    • Named human approvers on high-risk steps
    • Escalation, delegation and SLAs built in
    • Who approved, who declined, and what the workflow did next
    Policy conformance
    • Workflow steps evaluated against Compass and Atlas policies
    • Conformant, exception, or awaiting approval recorded per step
    • Continuous evidence for SOC 2, HIPAA, EU AI Act and NIST AI RMF
    The boundary
    • Approval-only — Marshal never blocks a running workflow
    • Governs alongside the pipeline, never inside it
    • If Marshal is unavailable, customer workflows keep running

    How the suite works together

    Meridian is sequenced the way real AI and IT programs mature — diagnose first, govern next, oversee continuously, measure momentum against reality, then extend the same discipline to the agents now acting on your behalf.

    1. 1

      Diagnose with Radar

      A free 8-domain assessment establishes your composite readiness score and surfaces the highest-leverage gaps.

    2. 2

      Author the policy with Atlas

      The guardrails you will be judged on, written, versioned, and turned into controls with a named owner.

    3. 3

      Attest it with Compass

      Obligations mapped to the frameworks that impose them, scored, timelined, and assembled into a package an auditor will accept.

    4. 4

      Govern clinical AI with Slant

      Bias, drift, and accreditation readiness scored continuously across every clinical model in production.

    5. 5

      Oversee the rest of your AI stack with Sentinel

      Trace Logic and the 8-domain Ethics Gate catch unsafe reasoning, drift, and bias across any LLM or ML tool.

    6. 6

      Collect the evidence with Ledger™

      Always-on evidence collection and control monitoring, so a control that quietly stopped working is visible now rather than at the next audit.

    7. 7

      Report to the board with Pulse

      Live risk telemetry across internal, third-party and AI systems, with the basis of the posture stated alongside the number.

    8. 8

      Prioritize with Signal

      The AI momentum score and Tension Resolver tell leadership where ambition is outrunning actual governance readiness.

    9. 9

      Discover your agents with Tether

      Every autonomous agent you run — including the ones nobody registered — inventoried, baselined, and watched for drift against its own history.

    10. 10

      Prove the workflow with Marshal

      The chain of prompt, tool, data, decision and actor captured end to end, with named human approval on the steps that carry real risk.
