Features, pricing, ratings, and pros & cons — compared head-to-head.
Allentis Network Diode (Tapics) is a commercial ot network segmentation tool by Allentis. OPSWAT MetaDefender NetWall is a commercial ot network segmentation tool by OPSWAT. Compare features, ratings, integrations, and community reviews side by side to find the best ot network segmentation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market teams protecting critical OT infrastructure from IT-sourced malware will get the most from OPSWAT MetaDefender NetWall because its hardware-enforced unidirectional data flow eliminates the attack surface entirely, not just monitors it. The combination of support for industrial protocols like Modbus, DNP3, and OPC with multiscanning across 30 antivirus engines and deep CDR file sanitization covers both the OT/IT boundary problem and supply chain risk simultaneously, addressing NIST GV.SC and PR.DS priorities that most network segmentation tools leave incomplete. Skip this if you need bidirectional communication for remote diagnostics or if your OT environment runs predominantly proprietary protocols that MetaDefender hasn't certified yet; unidirectional gateways are a design choice, not a limitation to work around.
