Introducing Bitsight Beacon™: Supply Chain Exposure Management for the SOC

The ripple effects of a cyberattack rarely stay contained.

Modern organizations rely on vast ecosystems of vendors, suppliers, SaaS providers, and partners. As those connections deepen, so does the potential blast radius of a third-party compromise. What begins as an exposed system or stolen credential inside a vendor environment can quickly cascade across the supply chain.

Attackers understand this. Increasingly, they target trusted third parties as an indirect path into larger organizations. According to Verizon’s 2025 Data Breach Investigations Report, 30% of breaches involved a third party. Gartner predicts that by 2026, 45% of organizations worldwide will experience a software supply chain attack, a threefold increase from 2021.

Yet most security teams still struggle to detect vendor-related threats before they escalate into incidents. And the challenge goes beyond just identifying third-party risk. Organizations seem to be baffled about operationalizing detection, investigation, and remediation, all actions that must be taken before a ripple across the supply chain becomes a wave.

The supply chain risk operational gap

Most organizations already rely on a mix of continuous monitoring platforms, threat intelligence feeds, breach alerts, and manual coordination between security and risk teams to manage supply chain risk. These workflows are often fragmented, reactive, and difficult to operationalize at scale. Signals arrive from multiple systems, ownership between teams is unclear, and vendor-related investigations can take days to reach positive remediation.

At the center of the problem is a disconnect between Security Operations (SOC) and Third-Party Risk Management (TPRM) teams.

SOC teams have the technical expertise to investigate threats, but limited visibility into vendor environments where early signs of compromise often appear, along with the business context needed to assess vendor criticality and impact. TPRM teams manage vendor relationships but often lack the operational context, telemetry, and threat intelligence needed to validate and remediate active threats quickly.

The result is a persistent operational gap. SOC teams can identify potential risk but cannot directly engage vendors, while TPRM teams can engage vendors but often rely on incomplete or delayed technical context to act.

At the same time, regulatory frameworks such as DORA and NIS2 are increasing pressure on organizations to demonstrate continuous monitoring, rapid response, and measurable supply chain risk reduction.

Organizations need a better way to detect, validate, and remediate threats across their vendor ecosystem before they escalate into breaches.

The solution: Supply Chain Exposure Management with Bitsight Beacon

Bitsight Beacon, Bitsight’s Supply Chain Exposure Management solution, helps SOC and TPRM teams detect and remediate threats across critical vendors and suppliers before they escalate into incidents.

Bitsight Beacon continuously monitors third-party environments across the supply chain attack lifecycle to identify real threats earlier, including:

• Pre-incident: Infrastructure exposure: Continuously identify critical weaknesses across a vendor’s attack surface that attackers can exploit for initial access, including exposed services, vulnerable systems, and actively exploited CVEs.
• Active intrusion: Malicious activity: Detect real-time operational evidence that a vendor’s infrastructure is linked to malicious activity, including botnet infections, command-and-control communications, and threat actor operations.
• Post-compromise: Breach evidence: Identify confirmed breaches, exposed credentials, initial access broker listings, ransomware activity, and vendor-related data circulating across underground forums, often before the vendor publicly discloses the incident.

Behind the scenes, Bitsight Beacon combines attack surface intelligence, supply chain mapping, and deep threat intelligence capabilities to continuously validate and correlate signals across the vendor ecosystem.

That includes actively exploited vulnerabilities, ransomware activity, botnet infections, stolen credentials, initial access broker (IAB) listings, and threat actor reconnaissance. Instead of forcing teams to chase fragmented indicators across disconnected tools, Bitsight Beacon delivers validated, high-confidence alerts enriched with context, including IOCs, MITRE ATT&CK mappings, evidence packages, and remediation guidance.

Move faster without adding operational noise

Rather than overwhelming analysts with raw telemetry and low-confidence findings, Bitsight Beacon continuously validates and prioritizes the threats that matter most across the supply chain attack lifecycle.

And because detection alone is not enough, Bitsight can also help organizations drive remediation. With managed vendor outreach, Bitsight Professional Services can directly engage affected vendors, share evidence and remediation guidance, track progress, and coordinate follow-through until issues are resolved.

The result is a more connected workflow between SOC and TPRM teams, giving organizations earlier visibility into vendor-related threats and helping accelerate detection, response, and remediation across the supply chain.

As supply chain attacks continue to grow in scale and sophistication, organizations need visibility beyond their own perimeter. Bitsight Beacon helps security teams detect threats earlier, validate real risk faster, and take action before a ripple across the supply chain becomes a wave.
