Featured Interview: Sumed Thakar (Qualys) on the Shift to Business Risk Management in Cybersecurity
[13:56–26:28]
Introduction & Context
Host Dave Bittner catches up with Sumed Thakar at RSAC 2026 to discuss how cybersecurity priorities are changing, how organizations are responding, and the growing focus on managing real, measurable business risk.
Major Discussion Points & Insights
The Constant Pace of Change in Cybersecurity
- "All we have seen in the last many years is just a continuous change in the industry. The rate of change has just accelerated in the last few years." —Sumed Thakar [15:17]
- Each tech shift (virtualization, cloud, now AI) introduces new risks; cybersecurity’s core is risk management, not tracking every “hot” tech.
Risk Management Over Dashboard Tourism
-
"Cybersecurity is essentially a risk management exercise for a company to not have financial loss from a cyber attack."
-
Key Point: True value is not number of detections or dashboards, but reduction in real risk of loss. The "risk operations center" (ROC) is likened to the transformation from reactive security to proactive risk reduction. [16:00]
“The most important dollar you can spend in cyber is actually getting things fixed. Otherwise, you’re just doing dashboard tourism… and we’re not getting anything fixed.” —Sumed Thakar [16:55]
The CISO’s Real Pain Points
-
CISOs’ top priorities are often different from their pain points:
- Priorities: evaluating new tech, compliance, detection.
- Pain points: Justifying budgets, demonstrating value to the board, overcoming detection/remediation fatigue.
“The pain point is going to my CFO and asking for more budget. And the CFO asks, well, so what do I get in return?” —Sumed Thakar [18:57]
- Difficulty translating cyber actions (patches, alerts) into meaningful business outcomes.
Alert Fatigue, Detection Fatigue, and the Need for Prioritization
-
There are more alerts than teams can remediate; not everything can be fixed.
-
The future: prioritize efforts that yield maximum reduction in risk, rather than chasing every vulnerability.
"You don’t have enough budget to fix everything that is detected, which means prioritization is not an option… what causes the most risk of loss?" —Sumed Thakar [17:35]
Agentic AI: Augmenting Security Teams
-
Agentic AI is a potential game-changer, addressing both talent shortages and operational fatigue.
“We have Agent Sarah, who is a Patch Tuesday agent… Now I’m augmenting my team with six AI agents… my team now is spending less of their time doing these kind of tasks, and they are leveraging Agent Sarah.” —Sumed Thakar [21:40]
-
Attacker adoption of AI is parallel; defenders must automate and scale with AI, but often lack budget/resources to hire AI devs.
-
Vendor solutions will play a central role, allowing organizations to scale up agentic AI without building internal teams from scratch.
Guardrails, Adoption & Trust in AI
-
Thakar acknowledges valid concerns about AI guardrails but sees them as part of cyclic tech adoption (cf. early cloud skepticism).
- Questions about data location, training, guardrails, and jailbreaking are important—but will not halt AI’s progress.
“Even within the last few months, the conversation has shifted from, ‘oh my God, I’m concerned my users…are using AI’… now you’re saying, ‘well, I’m concerned about the employees that are not using AI.’” —Sumed Thakar [24:42 & 25:57]
- Developers and vendors must ensure comprehensive safeguards and maintain customer comfort as adoption accelerates.
Notable Quotes & Memorable Moments
-
On dashboard fatigue:
“Otherwise you’re just doing dashboard tourism by building more dashboards. And we’re not getting anything fixed.” —Sumed Thakar [16:55]
-
On CISOs’ biggest reporting challenge:
“The pain point is going to my CFO and asking for more budget…should I give it to you and you are saying you cannot even tell me if you’re going to reduce the risk by five times, one time, three times.” —Sumed Thakar [18:57]
-
On agentic AI augmentation:
“I’m augmenting [my team] with six AI agents…they are leveraging Agent Sarah to do a lot of the tasks that needed to be done.” —Sumed Thakar [21:40]
-
On the shifting corporate AI discussion:
“Now you are saying, well, I’m concerned the employees that are not using AI. So it’s like, can I get a report of everybody who’s not using AI now?” —Sumed Thakar [24:42; 25:57]
Final (Lighthearted) Segment: Jonathan the Tortoise’s “Demise” Debunked
[27:00+ (approx.)]
- Viral fake reports claiming the death of Jonathan, the world’s oldest known land animal, were traced to a fraudulent social media post soliciting cryptocurrency.
- Jonathan is alive and well; lesson: always verify sources before reacting online.

Summary Takeaway
CyberWire’s April 2, 2026 episode emphasizes the need for the cybersecurity industry to refocus from chasing trends and individual “hot” threats toward real, measurable management of business risk. The episode’s news review shows attackers continually innovating, but the interview with Sumed Thakar shows how, by prioritizing what matters, operationalizing risk, and adopting new approaches like agentic AI, defenders can move from reactive fatigue to proactive value—if they can communicate that value to business stakeholders and boards.
