Bishop Fox

Offensive cybersecurity services and risk management

Overview

Bishop Fox focuses on offensive cybersecurity, testing clients’ networks and applications against real-world attack techniques to find and fix vulnerabilities before attackers exploit them. Its flagship Cosmos blends automated scanning with expert testing to continuously identify and remediate high-risk exposures on dynamic attack surfaces. Unlike many firms that rely on point-in-time tests, Bishop Fox emphasizes hands-on, real-world attack simulations and ongoing remediation across a broad set of services. The goal is to help organizations continuously reduce risk by exposing and closing security gaps before they can be exploited.

Penalizing Hospitals Won’T Stop Ransomware: Why Collaboration, Not Fines, Is Key To Healthcare Cybersecurity

Chris Bowen, Founder and CISO, ClearDATAThe recent $50 million initiative announced by the Advanced Research Projects Agency for Health (ARPA-H) can’t hurt in the ongoing battle against ransomware in the healthcare sector. This investment is aimed at strengthening the cybersecurity defenses of hospitals nationwide, protecting sensitive patient data, and enhancing the resilience of healthcare systems against cyber threats. However, I must emphasize that while $50 million is a step in the right direction, it is merely a drop in the bucket given the scale of the problem. For years, the healthcare sector has been a prime target for cybercriminals, with ransomware attacks becoming alarmingly frequent and increasingly destructive. Major organizations like Change Healthcare and Ascension have faced significant disruptions due to these breaches. The 2023 Ponemon Institute report indicates that 45% of healthcare organizations experienced a ransomware attack, with 67% of those incidents causing significant disruptions to patient care. These attacks not only compromise patient data but also jeopardize the delivery of essential healthcare services, potentially endangering lives. The introduction of ARPA-H’s Universal PatchinG and Remediation for Autonomous DEfense (UPGRADE) program is a timely and necessary intervention. A Proactive Approach to Cybersecurity The UPGRADE program aims to develop a comprehensive and scalable software suite to enhance the cybersecurity posture of hospitals. By reducing the patching time for vulnerable healthcare products from months to mere days, UPGRADE seeks a transformative shift in how hospitals can defend against cyber threats. The initiative focuses on four key areas:  creating a vulnerability mitigation platform developing high-fidelity digital twins of hospital equipment rapidly detecting software vulnerabilities developing defenses for each identified vulnerability These technical goals represent a proactive approach to cybersecurity, moving away from the reactive measures that have characterized the healthcare sector’s responses in the past. For instance, developing digital twins will allow hospitals to simulate and test the impact of patches and updates in a controlled environment, thereby reducing the risk of unintended consequences that could disrupt patient care and providing hospital staff and patients with much-needed confidence and peace of mind. Penalties Are Counterproductive Despite the strategic direction of the UPGRADE program, it is crucial to reconsider how regulatory bodies like the Office for Civil Rights (OCR) approach cybersecurity in healthcare
