Industry Guides
OT Asset Discovery
Asset discovery is the logical starting point when it comes to implementing OT cyber security in manufacturing. Without a clear view of assets and connections, it is difficult to make informed decisions about protection, risk, or compliance.
OT Compliance
Security frameworks are the most effective way to approach OT security systematically. From NIS2 to IEC 62443 they provide structure and help organisations implement repeatable security processes.
“From design to operate, Harpoon’s framework made complex work feel simple, personable and not overwhelming.”
