Market surveillance that explains itself
Sentri watches every order, trade, quote, and news event in real time, flags market abuse the moment it happens, and hands your compliance team an explained, evidence-backed case instead of a raw number. Deterministic detection you can defend to a regulator, with an AI layer that does the reading for you.
Deploys on-premise or inside your own cloud account. Single-tenant. Your data never leaves your perimeter.
Every event flows through a deterministic core, then an advisory layer, into an explained case.
The problem
Surveillance teams are drowning, and the abuse is getting smarter
Compliance desks at trading venues face the same four pressures, and most tooling makes at least one of them worse.
Alert fatigue
Too much noise, not enough signal
Legacy systems fire thousands of bare alerts a day. Analysts spend most of their time rebuilding context by hand before they can judge a single one. The real abuse hides in the backlog.
Cross-product manipulation
Blind spots between products
Manipulation increasingly spans a future and its underlying, a bond and its CDS, an index and its constituents. Surveillance siloed per product or per venue cannot see the pattern that lives between them.
Defensibility
Scores you cannot explain
A black-box risk score is not an answer a regulator accepts. When an authority asks why an alert fired, you need the exact rule, the exact parameters, and the exact events, not a model's best guess.
Operational risk
Outages mid-trading-day
Surveillance that drops events or stalls during a failover leaves a gap in the record. For a regulated venue, an unmonitored window is a reportable failure, not an inconvenience.
The solution
Rules surrounded by AI, not rules replaced by AI
Sentri keeps a deterministic detection core as the system of record and wraps it in an intelligence layer that does the analyst's reading. You get the speed and judgement of AI with an answer you can still defend.
- Detection core deterministic rules
- AI advisory clusters, narrates, ranks
- Model runtime self-hosted in your perimeter
Deterministic detection core
Twenty-three production rule types across five abuse families run on every event. Each alert names the rule, the parameters, and the underlying events. Reproducible, auditable, and defensible to the letter.
An advisory intelligence layer
AI reads each alert the way a senior analyst would: it clusters related alerts into one case, drafts the narrative, ranks by genuine risk, and surfaces the cross-product pattern. It advises. It never overrides the rule.
A self-hosted model runtime
Models run inside your perimeter on hardware you control. No event, order, or client identifier is sent to an external service. The intelligence layer is an asset you own, not an API you rent.
How it works
Two planes, one pipeline
Every event flows through a deterministic detection plane that decides what is and is not an alert, then an intelligence plane that decides what is worth a human's attention first.
Detection plane
System of record- 1Ingest orders, trades, quotes, and news through per-asset-class adaptors
- 2Merge feeds into a single time-ordered stream for cross-event correlation
- 3Run all rules on every event with loss-free, low-latency processing
- 4Raise a deterministic alert with full evidence the moment a pattern matches
Intelligence plane
Advisory- 1Cluster related alerts into a single investigable case
- 2Draft the case narrative and rank it by genuine risk
- 3Surface cross-product and cross-participant links a single rule cannot see
- 4Hand the analyst an explained case, ready for four-eyes review and reporting
Coverage
Twenty-three rule types, five abuse families, every asset class
Out-of-the-box detection tuned per asset class, from CDS and interest rate swaps to cash bonds, commodities, FX, and equities. Every rule is parameterised, suppression-aware, and audit-logged.

Why it matters
Fast enough for the tape, lean enough for the desk
Loss-free, low-latency ingestion on commodity hardware.
AI assembles context so people spend time deciding, not collecting.
Clustered with replicated event logs. No unmonitored window.
Across five abuse families and every supported asset class.
Figures are design targets for the platform under active development, not audited benchmarks.
Deploy
Runs where your data is allowed to live
Single-tenant by design. Sentri deploys into your environment and stays there. You keep custody of every event, every model, and every record.
On-premise or your own cloud
Run Sentri in your data centre or inside your own cloud account. The same single-tenant build, deployed wherever your data is allowed to live.
Your data never leaves
On-premise can be fully air-gapped. In the cloud, it runs inside your VPC with no egress. Sentri operates no shared service and sees none of your traffic.
Self-hosted models
The AI layer runs on hardware you control, in your perimeter. No orders, events, or client identifiers are ever sent to a third-party model API.
Built for the regulator
Full transaction logs, history tracking, indexed search, and four-eyes approval before any case is closed or escalated. Reporting maps to FCA, SEC, MAS, ASIC, and more.
