Blackwell Security, Acquired by Ostra Security

Ostra Security, which acquired Blackwell Security, is a managed security services provider founded in 2018 by Michael Kennedy. The company delivers managed SIEM, detection and response, endpoint protection, and strategic security advising to businesses seeking enterprise-level protection without building large internal security teams.

Ostra operates through three service tiers: Essentials (SOC monitoring), Core (managed EDR with SOC collaboration), and Plus (complete managed security stack). The company emphasizes operational accountability, actively managing and tuning client security tools rather than simply sending alerts. Their approach integrates with existing security investments from vendors like Microsoft, SentinelOne, Palo Alto, and AWS.

The company positions itself as providing Fortune 100-level security capabilities to mid-market organizations. Their model includes direct access to security professionals, real-time threat response, and ransomware resiliency services.

Organizations should consider Ostra when they need to transition from reactive alert management to proactive security operations without building a full internal SOC. The company's tiered approach allows businesses to start with focused monitoring and scale to comprehensive managed security as needs evolve.

Ostra's emphasis on operational accountability and tool optimization makes them suitable for companies with existing security investments that are underutilized. Expect hands-on collaboration, with security professionals who learn your environment and provide direct support rather than ticket-queue interactions.

The website does not demonstrate specific healthcare vertical expertise, HIPAA compliance certifications, or healthcare client examples. While Ostra's managed security services could support healthcare organizations, there is no visible specialization in healthcare-specific compliance requirements, BAA availability, or experience with healthcare-focused security challenges such as medical device management or EHR protection.

Mid-sized businesses with 50-500 employees that have invested in security tools but lack dedicated security operations expertise. Organizations facing alert fatigue or underutilized security investments seeking a partner to operationalize their protection while maintaining visibility and control over security outcomes.
