Respectfully responding to Divergent’s concerns:
You've raised important points about the risks of unpatched CVEs and the limitations of relying too heavily on sandboxing. I’d like to offer a different perspective on Comodo’s approach, especially in the context of real-world threat models.
Defense in Depth vs. Practical Containment Comodo’s containment model isn’t about trusting a single layer—it’s built around a default-deny strategy that has proven highly effective against non-targeted attacks. The sandbox is just one part of a broader system that includes script analysis, file reputation, and behavior blocking. This layered approach has consistently stopped threats that bypass traditional AVs.
Obscurity vs. Attacker Economics While CVEs are public and monitored, most attackers prioritize high-yield targets. Comodo’s lower market share makes it less attractive for mass exploitation. That’s not “security through obscurity”—it’s understanding attacker behavior. Most malware is designed to bypass mainstream AVs, not niche setups like Comodo’s.
Vendor Responsibility and Context Yes, vendors should patch vulnerabilities. But Comodo’s architecture means some CVEs may pose less practical risk due to containment. That doesn’t excuse delays, but it does offer context. The goal should be continuous improvement, not blanket dismissal.
User Choice and Risk Tolerance Labeling Comodo users as “complacent” overlooks the fact that many are power users who understand the trade-offs. They choose Comodo because its model aligns with their security philosophy. Informed practicality is not passivity.
In short, your critique is grounded in best practices, but it may underestimate the effectiveness of Comodo’s unconventional strategy in real-world scenarios. Let’s keep pushing for higher standards—while also recognizing that innovation doesn’t always follow the expected path.
Defense in Depth vs. a Compromised Foundation
You're correct that Comodo's model is a layered approach. However, the principle of "defense in depth" applies to the entire system, not just the sandbox. The critical CVEs we are discussing are "internal flaws in the security product's own trusted components", like the update mechanism.
A compromised updater with "SYSTEM privileges" (like CVE-2025-7096) renders every other "layer" irrelevant. That's not defense in depth, it's a compromised foundation.
Attacker Economics
Opportunity vs. Popularity
This view of "attacker economics" is dangerously outdated. While the development of complex, "zero-day" malware is targeted, the exploitation of *known, high-severity CVEs is often "automated and opportunistic".
Scanners are constantly searching for "any" unpatched system vulnerable to a known RCE. To an automated scanner, a vulnerable Comodo installation isn't a "niche target", it's simply a target. The cost to exploit is low, and the potential reward (SYSTEM access) is high, regardless of market share.
Vendor Responsibility is Not Contextual for Critical Flaws
The "context" you're offering is that the vendor believes their containment model justifies an absent patch for a critical vulnerability. This is a fundamentally flawed approach to risk management. The industry standard is to "patch critical vulnerabilities, period". Using one feature (the sandbox) as a reason "not" to fix a flaw in another critical component (the updater) is a dangerous precedent that no security professional should endorse.
Informed Choice Requires Acknowledging the Full Risk
"Informed practicality" is exactly what this discussion is about. A user can only be truly "informed" if the risks are presented clearly. Downplaying a critical RCE in a trusted update process as a "trade-off" is misleading. The real trade-off here isn't one feature versus another, it's accepting a vendor's poor security posture versus choosing one that adheres to basic standards of accountability.
In short, while Comodo's containment model is powerful in theory, it cannot be used as a shield to excuse fundamental failures in vendor responsibility and basic security hygiene.
