Security’s Blind Spot: The Threats Hiding in “Low-Severity” Alerts May 6, 2026
Security operations centers (SOCs) operate under a difficult reality where there are far more security alerts than human analysts available to investigate them. As organizations expand their digital environments and deploy more security tools, alert volume continues to grow faster than teams can realistically manage. AI is really just another layer that accelerates the volume […]

According to a report by Reuters, there are talks of reducing the time frame from the current two or three weeks down to just three days, dramatically raising the pace of defensive operations across government systems. These conversations, initiated by CISA and the […]

How Iranian Cyber Intrusions Unfold Inside Enterprise Networks May 5, 2026
Iranian cyber operations have gone from being disruptive single events to ongoing campaigns against governments, infrastructure providers, technology companies, and research organizations. Their ability to operate inside the same tools and infrastructure that defenders rely on makes these intrusions difficult to detect. The stakes extend well beyond espionage. For example, in 2022, Iranian-linked attackers caused […]

Visual data is the blind spot in enterprise security: that’s about to change May 4, 2026
Most enterprise security teams can tell you exactly how their databases are encrypted. They know who has access to their CRM and can pull audit logs for every sensitive document that’s been opened, copied, or shared in the last 90 days. Ask those same teams what’s happening with the thousands of hours of video footage […]

The new rules of war have no rules April 29, 2026
When the Iran conflict escalated the way it did, most businesses had no playbook for it. The disruption didn’t stay in the region. It showed up in energy supplies, financial systems, hospitals, and communication networks, touching organisations that had simply been going about their day.
