What is Defense in Depth?
Using different security vendors to protect endpoints and servers can be a strategic decision based on technical, operational, and risk management factors.
Here’s why schools might choose to diversify their security stack between servers and end user devices:
Defense in Depth
Layered security
Different vendors may specialize in different types of threats. By using multiple vendors, you reduce the risk of a single point of failure.
Endpoint vs. server threats
Endpoints (like laptops and mobile devices) face different threat vectors than servers (which are more likely to be targeted by lateral movement, privilege escalation or ransomware payloads).
Vendor Specialization
- Endpoint protection vendors often focus on user behavior, phishing protection, and device control.
- Server protection vendors may offer stronger capabilities in memory protection, application whitelisting and runtime protection for workloads.
Operational Segmentation
- Different teams may manage endpoints and servers (e.g., IT vs. DevOps orSecOps) and each team may choose tools that best fit their workflows.
- Compliance or regulatory requirements might dictate specific protections for servers (especially in finance, healthcare or government sectors).
Risk Mitigation & Vendor Lock-in
- Avoiding vendor lock-in: Relying on a single vendor can be risky if they suffer a breach or go out of business.
- Reducing blast radius: If one vendor’s solution is compromised, the other layer may still be secure.
Performance & Compatibility
- Some endpoint agents may be too resource-intensive for servers, especially in high-performance environments.
- Server protection tools may be optimized for virtual machines, containers or cloud workloads which endpoint tools may not handle well.
Visibility & Analytics
- Using different vendors can provide broader telemetry and cross-validation of alerts.
- Some organizations use a SIEM or XDR platform to correlate data across vendors for better threat detection
