Advanced Zero-Trust Implementation for K–12 Districts
Aaron Bugal, field CISO for Sophos, explains that zero trust is a journey, not necessarily a specific technology choice or stack. Rather, it is a blend of process, people and technology.
He says that identity has become the new security perimeter, requiring phishing-resistant, auditable, multifactor authentication to verify users and devices continuously.
Network segmentation limits the blast radius of breaches, while modern firewalls combining software-defined WAN, VPN and zero-trust capabilities simplify secure access. Continuous verification and automation enhance visibility and reduce manual workload, maintaining “transient trust” that adapts in real time.
“Around-the-clock detection and response are essential, making 24/7 monitoring and early alert investigation critical,” Bugal says. He adds that leveraging external expertise and automation can strengthen defenses and free teams to focus on strategic risk reduction.
WatchGuard field CTO Adam Winston says that when integrating EDR with SIEM and SOAR platforms, the goal should be to measure efficiency in the security operations center.

This can be achieved by setting up metrics, such as mean time to respond or contain, and running regular simulations to identify areas for improvement, without the pressure of real-world scenarios. “Organizations should start by ensuring that their EDR telemetry feeds directly into the SIEM to provide centralized visibility,” Winston says.
Teams can then use breach and attack simulation tools to routinely test the detection of new threats.
Winston adds that it’s important to tune SOAR playbooks based on test results to improve automated containment and facilitate case enrichment. “That way, teams can validate that the data is normalized and consistent across EDR, SIEM and SOAR for accurate correlation,” he says.
Continuous Exposure Management Strategies
Michelle Abraham, senior research director for security and trust at IDC, says visibility into all of an organization’s assets is the foundation of exposure management. “The asset data should be aggregated and managed holistically, so all risks can be managed as one instead of in silos,” she explains.
Once the exposures and their associated assets are prioritized based on their importance to the organization, remediation or mitigation efforts remove or block exposures from being exploited by attackers.
“Since exposures are found faster than ever, organizations need to move more quickly to fix issues as well,” Abraham notes.
Dana Simberkoff, chief risk, privacy and information security officer at AvePoint, says identity threat detection and response (ITDR) naturally complements zero-trust architectures by ensuring even verified, authenticated users are behaving within expected parameters.
“Your users — humans — are always going to be your weakest link,” Simberkoff says. “By focusing not only on identity but also on content and context, you can help make sure that human error does not lead to catastrophic consequences.”
Winston adds that a mature ITDR solution should respond to account creation and removal and continuously detect and respond to identity misuse across sessions, devices and behaviors.
