Dan Streetman Joins the SecurityScorecard Board

SecurityScorecard has appointed Dan Streetman, Chief Executive Officer of Tanium, to its Board of Directors as an independent director.  

For boards and CEOs navigating escalating third party exposure, cyber insurance scrutiny, and expanding regulatory oversight, this board appointment signals where the cyber ratings market is headed. Ratings have become an executive language for cyber posture, vendor governance, and board reporting. SecurityScorecard’s platform continuously rates more than 12 million entities worldwide, giving enterprise risk leaders a scalable way to quantify cyber posture across large vendor ecosystems.  

Why this board appointment matters

Cyber risk increasingly concentrates outside the four walls of the enterprise. Cloud providers, SaaS platforms, consultants, logistics partners, and software supply chains are part of core operating models. That exposure pushes boards toward measurable, comparable signals that support governance decisions.

SecurityScorecard operates directly in that board-level workflow. The company positions its ratings as a quantitative input for third-party risk management, board reporting, due diligence, cyber insurance underwriting, and regulatory oversight.  

Dan Streetman adds a distinct edge to this phase of the category.

1. Operator-level perspective on large-scale enterprise workflows
2. Security ratings become durable when they fit into how enterprises buy, remediate, and govern. Streetman has led global customer operations, product, and services across large enterprise environments, which maps to how SecurityScorecard expands adoption beyond security teams into procurement, finance, and executive reporting.  
3. Platform leadership in endpoint and operational control planes
4. Tanium focuses on autonomous endpoint management and real-time visibility, an operational layer that sits close to remediation and control. That lens complements SecurityScorecard’s external signal model by connecting measurement to practical action paths that resonate with CIOs, CISOs, and COOs.  
5. Board contribution shaped by high-tempo leadership environments
6. Security and resilience markets reward decision quality under pressure. Streetman’s U.S. Army leadership background adds a governance mindset centered on operational readiness, discipline, and execution in high-consequence environments.  

Dan Streetman’s leadership profile

Streetman serves as CEO of Tanium and sits on Tanium’s board, leading the company’s mission in autonomous IT and real-time endpoint intelligence.  

Prior to Tanium, he served as CEO of TIBCO Software and interim CEO of Allvue Software, with a track record of modernizing enterprise product portfolios and scaling performance.   He has also held senior leadership roles spanning large-scale, data-driven transformations at BMC, Salesforce, and C3.ai.  

SecurityScorecard highlights this blend of enterprise software leadership and cybersecurity domain expertise as core to the board's rationale behind the appointment.  

SecurityScorecard and the cyber ratings market

SecurityScorecard describes its ratings as easy-to-understand A to F scores driven by ten groups of risk factors, designed to support data-driven decisions about security posture and vendor performance.   This structure matters because it turns cyber posture into a common reference point for stakeholders with different incentives and vocabularies.

As cyber insurance underwriting tightens and third-party incidents continue to ripple through supply chains, boards increasingly seek signals that address three recurring questions.

1. Which third parties create the largest concentrated risk
2. Which issues show improvement velocity versus persistent exposure
3. Which remediation pathways deliver measurable posture lift inside a quarter

Security ratings platforms win when they answer those questions in a way that scales across thousands of vendors and supports repeatable governance.

SecurityScorecard also positions itself around supply chain detection and response and security risk ratings, reflecting a market shift toward continuous monitoring and risk programs focused on response.  

What boards and executives can take from this move

Streetman’s appointment provides a clear signal about the value of boards' capability profiles in the cyber ratings category.

1. Enterprise-scale product judgment
2. Cyber ratings sit at the intersection of data quality, methodology credibility, customer trust, and platform distribution. Boards increasingly prioritize leaders who have built and scaled platform products in complex enterprise environments.
3. Operational fit with remediation and control layers
4. Measurement creates value when it connects to action. Leadership with experience in endpoint, IT operations, and security control plane can help drive a tighter linkage between rating signals and remediation outcomes.
5. Credibility with buyers who span security, IT, finance, and risk
6. Vendor risk programs often live across functions. Boards benefit from directors who speak to CISOs and CIOs, while also engaging CROs, CFOs, and audit committees in practical governance decisions.

Christian & Timbers's perspective on board placement in cyber

Board placements in cybersecurity increasingly demand operating leaders who possess three attributes simultaneously.

1. Category understanding tied to buyer workflows
2. Platform scale experience across product and go-to-market execution
3. Governance readiness for risk, resilience, and regulatory oversight

Dan Streetman aligns with that profile. His enterprise software leadership background, combined with his experience with security-adjacent platforms and a disciplined execution style, supports SecurityScorecard as the category matures into a default layer of third-party cyber governance.
