How Do You Assess Vendor Risk?

Most organizations rely on a highly interconnected environment of vendors, suppliers, partners and service providers to extend their capabilities and scale operations. To address the growing third-party cyber risks, you need to strategically assess every vendor with privileged access to your systems, networks, and data. Start by asking yourself:

  • Do I have formal procedures to manage cyber risks associated with third-party access to my environment and data?
  • Have I thought about the supply chain in my vendors’ ecosystems and who else may have access to my data?
  • How can I ensure my data is protected if my third-party vendors are compromised?

The cost of a third-party breach is not just measured in short-term financial loss and lost productivity, but also in long-term reputational damage and client churn.

The best way to protect your company from a devastating breach is to avoid one in the first place – conduct the due diligence needed and have the right protection in place.

Consider the Three Ps of Third-Party Risk:
Policies, Prevention, and Promises

Threat actors often target critical service providers that are known to be trusted vendors, because if the attack is successful, they gain access to a downstream client base. Therefore, organizations need to bake security, by design, into their programs, products, and services.

To reduce your cyber risks, you need to assess the vulnerabilities and weaknesses of any third-parties that you rely on. So, consider the three Ps of third-party risk:


  1. Define Supply Chain Policies
  2. Develop Due Diligence Tools
  3. Establish Periodic Validation
  4. Raise Security Awareness
  5. Encourage Improvement

Understand what data you’re willing to share and the type of access you’re willing to provide to a vendor. These policies should be established before you engage with a potential third-party vendor.


  1. Identify Assets and Obligations
  2. Define Risk Appetite
  3. Conduct Risk Assessments
  4. Analyze Results and Risks
  5. Define Defensive Requirements

Identify the risks that may arise as a result of the policies. Then, work with your vendor(s) to establish the minimum security requirements needed to mitigate the risks and protect your business from potential cyber threats.


  1. Contractual Obligations
  2. Demark Responsibilities
  3. Establish Minimum Standards
  4. Document Notifications
  5. Representations/Warranties

Ensure that your vendor contracts consider how and when breaches will be disclosed, how breach information will be logged and shared, and who will be responsible for the remediation, forensic analysis, and damages.

Identify Your Risk of A Third-Party Breach

As a security leader, you must account for the lack of visibility and reduced end-to-end control the presence of third-party vendors has on your overall attack surface. eSentire is here to minimize your third-party risk with Exposure Management and Multi-Signal MDR services.

eSentire Third-Party Cyber Risk Management In Action

CASE STUDY: Fraudulent Transaction Illuminates Third-Party Risk

eSentire was engaged by a financial services firm to conduct third-party cyber risk assessments.

The firm previously failed an audit due to a fraudulent transaction from a compromised third party. Realizing the potential implications of a repeat issue, the client contracted eSentire’s Virtual CISO (vCISO) services, specifically a Third-Party Risk Assessment.

CASE STUDY: Third-Party Serves as Staging Point for Cryptojacking Attack Using Powershell

eSentire observed an unknown threat actor attempting to deploy Monero cryptocurrency mining malware to multiple customers. This increasingly common type of attack known as “cryptojacking” allows a hacker to leverage the computing power of devices to mine cryptocurrencies, unbeknownst to the victim.

Following an investigation from eSentire’s SOC, it was determined that the threat actor was leveraging a zero-day vulnerability in Kaseya’s Virtual Systems Administrator (VSA) agent to gain access to the clients’ network.

Read this case study to learn how eSentire remediated the attack.

WE OWN THE R IN MDR: The Kaseya Zero-Day Attacks

Watch this video with one of eSentire’s Elite Threat Hunters, Spence Hutchinson, as he reviews the Kaseya VSA supply chain attacks. Spence outlines how eSentire’s Security Operations Center (SOC) and Threat Response Unit (TRU) were able to quickly respond on our customer’s behalf and notify Kaseya of the breaches.

Modern Threat Response

In these attacks, threat actors leveraged zero-day vulnerabilities to push Cryptomining malware and ransomware to Kaseya VSA customers. Our proprietary BlueSteel Machine Learning Engine identified malicious Powershell commands being executed. eSentire’s actions to detect, respond and remediate these attacks demonstrate the importance of MDR services that go beyond alerting and host isolation to deliver complete & robust response.
