Lestr platform delivers predictive and
real-time information to monitor all your shipments and mitigate any kind of risks.

Connect sources

Lestr aggregates data from all relevant sources to help you anticipate risks and better monitor your shipments.

Carriers and freight forwarders

The number of shipping companies and freight forwarders supported makes Lestr the most complete solution. Lestr covers about 95% of the world maritime trade exchanges.

Marine trackers

Lestr leverages AIS data from different sources (CLS, Lloyd's List, etc.) to get real-time position of your cargo and checks the consistency of the shipping routes used by vessels.

Know your customers and vessels

Lestr identifies all entities involved in the shipment (vessels, shipper, consignee, registered owners of containers and vessels, etc.), qualifies them by collecting information from multiple open sources and screens them against custom, public or private sanction lists (OFAC, UN, World Check, Factiva, etc.).


Lestr detects high risk goods and gathers information from multiple sources (UN Comtrade, etc.) to analyse the consistency of the transaction and its price.

Your own data sources

Lestr relies on cutting-edge data fusion technology to connect your specific data sources in real-time.

Lestr relies on cutting-edge data fusion technology to automate multi-criteria and multi-source reconciliations which would be extremely time-consuming and complex to perform manually.

overview the journey

Lestr tracks your shipment at every step whatever the complexity of the trip.

Your shipment's journey

Follow your cargo from loading to discharging including transhipments, vessel port calls and pre/post shipments. Furthermore, the systematic cross-checking of AIS data emitted by the vessels with the scheduling information provided by the carriers makes Lestr one of the most accurate and reliable solution for goods tracking.

Use any information to start

Import a shipment from a bill of lading (through optical character recognition technology), a bill of lading number, a container number or a vessel (name or imo).

Autotrack your shipment

Dispose of a continuous tracking and be notified in case of route deviation and of discharging.

Record all entities for further analysis

Retrieve everything in one place: containers, vessels, carriers, goods, organisations, individuals, etc.

Anticipate trade risks

Lestr helps you secure your shipments and notifies you of all unexpected events.

Blacklisted ports and countries

Be alerted of any international sanctions breach.

Criminal activities

Screen organisations, individuals and vessels to prevent criminal activities. Detect documentary fraud (bill of lading verification), suspicious shipments (e.g. high-risk vessels, inconsistencies between goods and partner countries, etc.) and abnormal behavior of vessels (e.g. AIS gap).

Trade Mis-invoicing

Check if goods are priced outside typical ranges for comparable products. The deliberate manipulation of the value of a trade transaction is a well-established method of hiding illicit financial flows within the international commercial trade system, as well as evading and/or exploiting customs regimes.

High-risk goods

Detect high-risk goods such as dual-use goods, goods involving higher risk of money laundering, etc.


Provide predictive ETA and detect real-time delays thanks to cutting-edge algorithm. Each delay is analysed because it could mean that the ship has deviated from its course and has engaged in an illegal activity (e.g. illegal ship to ship transfer).

Be all on the same page

All your team members are connected, and so are your partners and customers. Everyone receives information in real-time to follow shipments.


Receive alerts for any unexpected events on a journey.

Share a shipment link

Allow any stakeholder to follow the shipment and get real-time status information.

Manage multiple operator levels

Allow your operators to escalate any suspicious shipment.

Work in your own office environment

Connect Lestr to your back office, case manager or collaboration (Teams, Slack, etc.) tools for a better collaboration.

Improve Decision-making

Be better informed to make a better decision.

Monitor your activity

Get full reports of all your shipments and generate a tamper-proof audit trail encompassing all controls that have been applied to each shipment.

Learn from your activity

Enhance protection against risks and make better informed decisions by capitalising on all your shipments. Each new shipment feeds a secured knowledge base on which machine learning algorithms are running to analyse trends and recognise patterns of fraud.

Be aware of your risks

Identify risks that are specific to your business domain, using our multi-faceted approach.
