Owl OPDS-100 vs Waterfall Security Solutions: Side-by-Side Comparison (2026)

Owl OPDS-100

Enterprise and mid-market security teams protecting critical infrastructure from lateral movement will find the Owl OPDS-100's hardware-enforced one-way data transfer uniquely valuable when network segmentation must survive active compromise. The 1U form factor and physical data diode design deliver the PR.IR control maturity that pure software segmentation cannot guarantee, especially in OT environments where the cost of failure justifies appliance-class hardware. Pass if your throughput demands exceed low-to-moderate rates or if you need east-west microsegmentation across hundreds of internal pathways; this tool is built for perimeter hardening and critical asset protection, not general-purpose network slicing.

Waterfall Security Solutions

Enterprise and mid-market teams running critical OT/ICS infrastructure will get the most from Waterfall Security Solutions because hardware-enforced unidirectional gateways actually stop lateral movement that software firewalls can't, turning network segmentation from a policy exercise into a physics problem. The tamper-proof Waterfall Blackbox forensic repository and centralized monitoring address the RS.MI and DE.CM gaps that plague most OT deployments, giving you provable incident containment when breaches happen. Skip this if you need bi-directional data flow between OT and IT networks or if your OT environment runs commodity IT protocols; Waterfall's strength is enforcing one-way trust boundaries, which means some legitimate use cases require workarounds like the WF-Secure Bypass emergency access mode.
