SERVICE
OT Security Advisory
Harpoon’s OT Security Advisory service gives you immediate access to senior experts who can be engaged on a flexible, call-off basis. This could be for reviewing architecture, redlining a policy, supporting board discussions, or providing input during incident response. Advisory days are pre-purchased and drawn down only when you need them, giving you access to expertise without procurement delays.
Key Benefits
This model provides agility and certainty. You get the benefit of senior, real-world OT expertise exactly when it’s required, without carrying the cost of a retained consultant or the delays of a new procurement cycle. Decisions are faster, risks are addressed earlier, and leadership benefits from clear, defensible advice.
