Meeting the OSFI E-21 deadline was step one. Demonstrating resilience is the work that follows.

The focus now is on evidence: can you demonstrate that critical operations will remain within tolerance during a cyber incident, technology outage, or third-party disruption?

What that evidence looks like:

➤ Scenario testing underway, progressing toward full coverage of critical operations by September 1, 2027
➤ Critical third-party dependencies mapped, assessed, and supported by contingency plans
➤ Clear board reporting on resilience, test results, gaps, and remediation
E-21 also works alongside B-10 third-party risk management. And with OSFI’s E-23 model-risk-management guideline taking effect May 1, 2027, the regulatory agenda is only expanding.

ISA Cybersecurity helps Canadian financial institutions build, test, and demonstrate cyber resilience.

What would actually happen if someone tried to break into your network right now?

Our team doesn't run scans and call it a day. We think like attackers – pivoting, escalating privileges, and exploiting the small gaps that can turn into serious breaches.

What you walk away with isn't just a report. It's clarity:
🔸Where you're exposed
🔸Which risks matter most
🔸What to fix first

Endpoints are one of the most targeted surfaces in your network. Protecting them requires constant vigilance - but that burden shouldn’t fall solely on your team.

For one Canadian medical manufacturing company, ISA Cybersecurity's Managed EDR service provides 24/7 defense without the overhead of building it in-house.

By partnering with ISA Cybersecurity, the internal team gained:
🗸 Improved visibility across their environment
🗸 Faster threat detection and response
🗸 24/7 monitoring by a dedicated external team
🗸 The freedom to stay focused on core operations

With endpoints remaining a top attack vector, your solution is only as effective as its last review.

ISA Cybersecurity's EDR Health Check ensures your endpoints are fully protected, agents are reporting correctly, and detection and response capabilities are optimized to stop threats in real time. Without regular reviews, misconfigurations and alert fatigue can limit effectiveness - and ROI.

The EDR Health Check helps organizations:
➡️Confirm agent deployment and endpoint coverage
➡️ Review policy configurations and alerting effectiveness
➡️Identify visibility gaps and response inefficiencies
➡️Improve threat detection and response readiness

Ensure your defenses are ready for what's next: https://hubs.li/Q047ndQf0

Cybersecurity’s Human Code: Enza’s Story on “Faces of Cyber”

We’re excited to share that ISA Cybersecurity Executive Vice-President Enza Alexander has been featured in Faces of Cyber, a national initiative that highlights the individuals driving cybersecurity forward. In this exclusive interview, she dives deep into what it really means to build cyber resilience with people in mind – not just hardware or code.

Enza reflects on her career journey from early tech roles to becoming a leading voice in OT and cybersecurity, emphasizing that the future of the industry is deeply human. She reflects how cybersecurity goes beyond technology – it’s about helping people navigate risk, uncertainty, and trust.

She also highlights the industry’s talent gap and the importance of building strong teams through community engagement and shared knowledge. Enza envisions the future of cybersecurity will be increasingly AI-driven – but must stay firmly rooted in ethical, human-centred practices. Her message is clear: collaboration, humility, and adaptable leadership will define the next chapter of cybersecurity.
