DefenseStorm CISO: William Wetherill

What the company sells

DefenseStorm sells a cyber risk management platform designed exclusively for U.S. banks and credit unions. DefenseStorm backs its platform with a 24X7 Collaborative SOC of banking-fluent cybersecurity analysts. DefenseStorm cites 200+ banks and credit unions alongside 16,000+ banking-specific controls mapped across industry control frameworks, regulatory guidance, and exam procedures.

DefenseStorm governs its AI capabilities with seven Built for Banking AI Principles, mapped to NIST AI RMF and CRI FS AI RMF. DefenseStorm states that every AI output is explainable to a non-technical professional. DefenseStorm describes AI capability as growing step by step, under explicit policy, with human-in-the-loop boundaries. DefenseStorm says 12 years of banking-only threat patterns, examiner expectations, and industry control frameworks inform every AI output.

DefenseStorm offers managed detection and response (MDR) built for the attack patterns, industry control frameworks, and operational realities of financial institutions. DefenseStorm states that a US-based, senior banking-fluent cybersecurity analyst collaborates with the customer on a case, 24x7x365. DefenseStorm analysts work alongside AI-enhanced triage to investigate with banking context and generate structured evidence for governance reporting. DefenseStorm describes a co-managed approach in which customers view configuration logs showing how their environment is monitored 24/7 by DefenseStorm cybersecurity experts.

GRID Active Threat Surveillance gathers and analyzes data from all types of sources, technology, tools, and systems and identifies threats in the customer's environment. GRID Active Threat Surveillance now includes an Incident Similarity feature that applies machine learning to incident monitoring and management. Customers can add EDR functionality and Vulnerability Management Services, both integrated with the GRID Active platform, to their cybersecurity risk management solution. DefenseStorm vulnerability scanning lets customers assess their system and discover weaknesses an adversary may be able to exploit. Employee Activity Monitoring is included with Threat Surveillance and monitors user access, permissions and actions. DefenseStorm integrations can include tools for intrusion detection, firewalls, threat intelligence platforms, and identity and access management systems. DefenseStorm has a team of cybersecurity experts covering implementation, product training and ongoing platform support. A DefenseStorm security engineer who began in 2020 developed DefenseStorm's EDR Service. DefenseStorm appointed its Director of Cyber Threat Intelligence in 2022, and that role is responsible for nearly all facets of the EDR service. DefenseStorm uploads IOCs related to a vulnerability into its ThreatMatch Feed.

DefenseStorm turns every alert, investigation, and decision into structured evidence mapped to CRI Profile, NIST CSF 2.0, and exam procedures. DefenseStorm offers continuous control monitoring across 16,000+ controls. DefenseStorm risk scoring is shaped by real alerts and incidents. DefenseStorm governance aligns to FFIEC examination procedures, GLBA Safeguards requirements, the NIST Cybersecurity Framework (including CSF 2.0), NCUA expectations, and the CRI Profile.

GRID Active Risk Assessment and Governance Package aligns an institution's risk and governance to evidence the effectiveness of control in its risk assessment. GRID Active Risk Assessment and Governance Package lets institutions filter risk assessments to create smaller assessments such as an eBanking risk assessment, or one large information security risk assessment encompassing all risks in the register. Pre-mapped Task Schedule templates schedule program activities, and the activities map into framework and self-assessment directives as evidence. DefenseStorm lets customers schedule governance and monitoring activities to align with their cyber security compliance program cadences. GRID Active Reporting lets financial institutions customize reports based on audience and timing. DefenseStorm's governance product is integration-ready across core banking, digital banking, authentication, and cloud platforms.

DefenseStorm unifies threat operations, risk intelligence, governance, and AI in GRID Active, its intelligent data engine. DefenseStorm states that one provider replaces separate SIEM, EDR, SOC, risk assessment, vulnerability management, brand management, security awareness training, and governance tools. DefenseStorm runs risk and governance on the same platform as its threat operations. DefenseStorm's governance product connects cyber risk assessments, control monitoring, evidence collection, and board reporting into one continuous program.

DefenseStorm describes its solution as co-managed, cloud-based and compliance-automated, designed specifically for the cyber threat and compliance demands facing the financial services industry.^{[1][4][5][6][7][8]}
