Talk to TheosSupply chain attacks exploit the trust organisations place in software, updates, and third-party integrations.
THE CHALLENGE
How supply chain compromises succeed.
Supply chain attacks doubled in 2025, with technology, IT, and telecommunications companies as the primary targets. In February 2025, a DPRK-nexus adversary executed one of the largest cryptocurrency thefts on record (1.46 billion USD) through a supply chain compromise of a digital asset management platform.
The pattern is consistent: adversaries compromise a trusted upstream provider, such as a software vendor, a development dependency, a SaaS integration, and use that trust to gain access to downstream organisations. The intrusion arrives through a channel that security controls are configured to allow.
Third-party dependencies, open-source packages, SaaS integrations, and managed service provider access each represent a trust relationship that adversaries can target. Organisations that have not assessed these relationships are operating on assumed security.
HOW THEOS ADDRESSES IT
What Theos delivers.
Vulnerability Assessment and Penetration Testing
Structured testing of third-party integrations, API connections, SaaS access paths, and software dependency chains against the exploitation techniques supply chain adversaries use. Findings identify the trust relationships that carry the highest risk and what controls would close the exposure.
Red Teaming
Adversary simulation that includes supply chain-style access paths, testing whether a compromise of a trusted third-party relationship could be used to gain access to your environment, move laterally, and reach high-value targets. Findings are calibrated to your specific supplier and integration landscape.
