Blackstone Real Estate Income Trust, Inc. - (BSTT)

10-K Filing Date: March 28, 2024
ITEM 1C. Cybersecurity

Cybersecurity Risk Management and Strategy

As an externally managed company, BREIT’s day-to-day operations are managed by the Adviser and our executive officers under the oversight of our board of directors. Our executive officers are senior Blackstone Real Estate professionals and our Adviser is a subsidiary of Blackstone. As such, we are reliant on Blackstone for assessing, identifying and managing material risks to our business from cybersecurity threats. Below are details Blackstone has provided to us regarding its cybersecurity program that are relevant to us.
Blackstone maintains a comprehensive cybersecurity program, including policies and procedures designed to protect its systems, operations, and the data utilized and entrusted to it, including by BREIT, from anticipated threats or hazards. Blackstone utilizes a variety of protective measures as a part of its cybersecurity program. These measures include, where appropriate, physical and digital access controls, patch management, identity verification and mobile device management software, annual employee cybersecurity awareness and best practices training programs, security baselines and tools to report anomalous activity, and monitoring of data usage, hardware and software.
Blackstone tests its cybersecurity defenses regularly through automated and manual vulnerability scanning, to identify and remediate critical vulnerabilities. In addition, it conducts annual “white hat” penetration tests to validate its security posture. Blackstone examines its cybersecurity program every two to three years with third parties, evaluating its effectiveness in part by considering industry standards and established frameworks, such as the National Institute of Standards and Technology and Center for Internet Security, as guidelines. Further, Blackstone engages in cyber incident tabletop exercises and scenario planning exercises involving hypothetical cybersecurity incidents to test its cyber incident response processes. Blackstone’s Chief Security Officer (the “CSO”) and members of Blackstone’s senior management, Legal and Compliance, Technology and Innovations (“BXTI”), and Global Corporate Affairs participate in these exercises. Learnings from these tabletop exercises and any events Blackstone experiences are reviewed, discussed, and incorporated into its cybersecurity framework as appropriate.
In addition to Blackstone’s internal exercises to test aspects of its cybersecurity program, Blackstone periodically engages independent third parties to analyze data on the interactions of users of Blackstone information technology resources, including Blackstone employees, and conduct penetration tests and scanning exercises to assess the performance of Blackstone’s cybersecurity systems and processes.
Blackstone has a comprehensive Security Incident Response Plan (the “IRP”), designed to inform the proper escalation (including, as appropriate, to BREIT’s senior management) of non-routine suspected or confirmed information security or cybersecurity events based on the expected risk an event presents. As appropriate, a Security Incident Response Team composed of individuals from several internal technical and managerial functions may be formed to investigate and remediate the event and determine the extent of external advisor support required, including from external counsel, forensic investigators, and/or law enforcement. The IRP sets out ongoing monitoring or remediating actions to be taken after resolution of an incident. The IRP is reviewed at least annually by our CSO and members of BXTI and Legal and Compliance.
Blackstone maintains a formal cybersecurity risk management process and cybersecurity risk register, designed to track cybersecurity risks at the firm, and integrates these processes into the firm’s overall risk management practices described above. Blackstone’s CSO periodically discusses and reviews cybersecurity risks and related mitigants with its enterprise risk committee and incorporates relevant cybersecurity risk updates and metrics in the semi-annual enterprise-wide risk management report.
Blackstone has a process designed to assess the cybersecurity risks associated with the engagement of third-party vendors, including those of companies externally managed by Blackstone such as BREIT. This assessment is conducted on the basis of, among other factors, the types of services provided and the extent and type of Blackstone data accessed or processed by a third-party vendor. On the basis of its preliminary risk assessment of a third-party vendor, Blackstone may conduct further cybersecurity reviews or request remediation of, or contractual protections related to, any actual or potential identified cybersecurity risks. In addition, where appropriate, Blackstone seeks to include in its contractual arrangements with certain of its third-party vendors provisions addressing best practices with respect to data and cybersecurity, as well as the right to assess, monitor, audit and test such vendors’ cybersecurity programs and practices. Blackstone also utilizes a number of digital controls, which are reviewed at least annually, to monitor and manage third-party access to its internal systems and data.
For a discussion of how risks from cybersecurity threats affect our business, and our reliance on Blackstone in managing these risks, see “Part 1. Item 1A. Risk Factors – Risks Related to Our Organizational Structure – Cybersecurity risks and data protection could

result in the loss of data, interruptions in our business, damage to our reputation, and subject us to regulatory actions, increased costs and financial losses, each of which could have a material adverse effect on our business and results of operations” in this Annual Report on Form 10-K.
Cybersecurity Governance

Blackstone has a dedicated cybersecurity team, led by Blackstone’s CSO, who works closely with Blackstone senior management, including Blackstone’s Chief Technology Officer (“CTO”), to develop and advance the firm’s cybersecurity strategy, which applies to BREIT.

Blackstone’s CSO and CTO have extensive experience in cybersecurity and technology, respectively. Blackstone’s CSO, Adam Fletcher, is a Senior Managing Director in BXTI and is responsible for all aspects of cyber and physical security across Blackstone.

Blackstone’s CTO, John Stecher, is a Senior Managing Director and head of BXTI. Mr. Stecher is responsible for all aspects of technology across Blackstone. Mr. Stecher also advises Blackstone’s investment teams and acts as a resource to Blackstone portfolio companies, and companies externally managed by Blackstone such as BREIT, on technology-related matters. Before joining Blackstone in 2020, Mr. Stecher was a Managing Director and the Chief Technology Officer and Chief Innovation Officer at Barclays. He was also a member of the Barclays Technology Management Committee.

Mr. Stecher received a BS in Computer Science from the University of Wisconsin – Madison and a MS in Computer Science from the University of Minnesota.
BXTI conducts periodic cybersecurity risk assessments, including assessments or audits of third-party vendors, and assists with the management and mitigation of identified cybersecurity risks. The CSO and CTO review Blackstone’s cybersecurity framework annually as well as on an event-driven basis as necessary. The CSO and CTO also review the scope of Blackstone’s cybersecurity measures periodically, including in the event of a change in business practices that may implicate the security or integrity of Blackstone’s information and systems.
BREIT’s board of directors is responsible for understanding the primary risks to our business. The audit committee of BREIT’s board of directors is responsible for reviewing BREIT’s and the Adviser’s IT security controls with management and evaluating the adequacy of BREIT’s and the Adviser’s IT security program, compliance and controls with management.
Blackstone’s CSO reports to both our executive officers as well as our board of directors and/or our audit committee annually on cybersecurity matters, including risks facing us and the Adviser and, as applicable, certain incidents. In addition to such annual reports, our board of directors and/or the audit committee receive periodic updates from Blackstone on the primary cybersecurity risks facing us and our Adviser and the measures we and our Adviser are taking to mitigate such risks, as well as on changes to our and our Adviser’s cybersecurity risk profile or certain newly identified risks.
