Problems We Solve

Practical OT cybersecurity improvement starts with the real engineering problem

Meridian helps industrial teams define the problem clearly, understand operational impact, and develop proportionate actions that can be delivered in live environments.

Problem areas

Flat OT Networks

Many industrial facilities still operate with flat OT networks where PLCs, HMIs, engineering workstations, historians, and third-party systems share common network paths.

See approach

Legacy Control Systems

Industrial sites often rely on older PLCs, SCADA platforms, unmanaged switches, unsupported operating systems, and vendor-specific communications.

See approach

IEC 62443 Compliance

Many projects reference IEC 62443 but lack a clear method for defining the system under consideration, security zones, conduits, target security levels, and verification evidence.

See approach

Project Cybersecurity Assurance

Cybersecurity requirements are often introduced late in control system projects, causing delays during design review, FAT, SAT, or client acceptance.

See approach

Insecure Remote Access

Industrial sites frequently depend on remote support connections that were added for maintenance convenience before formal OT security controls existed.

See approach

Poor Asset Visibility

Cybersecurity decisions are difficult when sites lack reliable records of PLCs, HMIs, switches, servers, engineering workstations, interfaces, and data flows.

See approach

Unmanaged Industrial Networks

Production networks often grow over time through unmanaged switches, temporary connections, and undocumented changes.

See approach

Supplier Package Integration

Vendor package systems are often integrated into wider control networks without enough review of interfaces, access routes, testing evidence, or support responsibilities.
