Use Cases

Third party risk

Third-party breaches accounted for 35.5% of all incidents in 2024, increasing by 6.5% annually as threat technologies evolve. These breaches span cybersecurity, compliance, financial, operational, and reputational risks. Tesari automates background verification by cross-referencing registries, court records, sanctions lists, and media data to reveal who truly stands behind a company name.

INVESTIGATIVE JOURNALISM

Journalistic investigations often take days or even weeks to gather data from multiple sources, translate it, and manually check its accuracy. Accessing hard-to-reach information makes the process even slower. Tesari completes this work in minutes by compiling, translating, and cross-referencing data from global registries, leaks, media, and court filings. It supports many languages, applies smart transliteration, and keeps every data point traceable to its source.

Litigation support

Inefficiencies in collecting and analyzing evidence slow legal investigations and due diligence. Tesari streamlines cross-referencing, background checks, and evidence discovery through a single interface integrated with multiple sources.

Supply chain Security

Global supply chains are complex and opaque, with countless intermediaries and hidden links. Tesari cross-references and validates corporate filings, ownership records, and leaked data, allowing investigators to map supplier and buyer networks, trace the origins of goods, and uncover high-risk connections or violations buried deep within multi-layered supply chains.

Insider threats

Social engineering, insider threats, and phishing attacks now account for up to 40% of all security breaches. With Tesari, investigators can assess the likelihood of impersonation attacks through behavioral pattern analysis, target prediction, and suspicious activity monitoring.

Fraud investigations

By cross-referencing publicly available information from social media, news reports, business registries, criminal watchlists, and other open data sources, verify the legitimacy of identities, and identify connections to high-risk individuals or organizations.

Enhanced Due diligence

Due diligence often takes days or weeks of research to complete a single report. Most companies struggle to access regional data, translate it accurately, cross-reference, validate, and analyze it before starting the report. Tesari compiles all relevant data and delivers real-time insights on individuals and companies, helping organizations make informed decisions with confidence.

Disinformation and influence operations

Disinformation moves quickly across borders, often hidden behind media fronts, shell firms, or digital proxies. Tesari connects media outlets, individuals, and organizations across languages and platforms, enabling investigators to uncover shared ownership, funding links, and coordinated narratives.

Law enforcement

Tesari enables law enforcement to uncover hidden connections in criminal, terrorist, and trafficking networks through AI-assisted data correlation and behavioral analysis. The platform consolidates global open-source intelligence into structured case files, helping investigators identify high-risk actors and act faster with confidence.
