Had a great time on the panel @HackRedCon today. Lots of interesting disucssion & the most debated one: "Do we expect to see auditors for things like SOC 2 start accepting AI-executed security assessments in the near future?" The panel was evenly split. What are your thoughts?

According to the SBA 60% of small businesses close within 6 months of a cyber breach, yet enterprise security testing often leaves organizations priced out. That Gap shouldn't exist so we built SIMAPTIC! bcsecurity.io/blog/introduci…

Cyber on the rise: In 2025, Taiwan experienced an average of 2.6 million daily cyberattacks on critical infrastructure, from hospitals to energy systems, up from the previous year. reuters.com/world/china/ch…
New year, new site, new tool! We’ve refreshed the BC Security website and introduced SIMAPTIC, our continuous threat-exposure and validation platform that simulates multi-stage attacks and gives teams real signals they can act on. simaptic.ai bcsecurity.io
Happy Holidays from all of us at BC Security! As the year winds down, we just want to say thanks to our clients, partners, and the awesome community around us. Your support means everything, and it’s what keeps us building, learning, and doing what we love. Thank you!!!

Cyber Monday Deal: Level Up Your Cyber Skills! One of our flagship cyber courses is going on sale, for a limited time. If you’ve been waiting to jump into hands-on, operator-level training, now’s your moment. training.bc-security.org/courses/empire…
AI-driven cyber-espionage is now real. Anthropic reports autonomous agents running full intrusion chains with minimal human input. Defense has to move at machine speed now. Full report: anthropic.com/news/disruptin…
Google’s AI Threat Tracker shows attackers using malware that rewrites itself in real time. Static defenses can’t stop code that adapts. Modern security needs behavior-based detection, strong identity controls, and real validation. Our defenses must learn faster!
Cybersecurity Awareness Month! Cyber Tip: Segment your administrative network and separate privileged access. Keep domain controllers, jump servers, and management systems separate from user workstations. Isolation limits lateral movement and protects privileged credentials.
