Top move

Centralise and standardise third‑party remote access: tool sprawl increases cyber risk and slows troubleshooting; gating vendor access through a single approved method reduces attack surface and speeds repairs

Key takeaways

  • Centralise and standardise third‑party remote access: tool sprawl increases cyber risk and slows troubleshooting; gating vendor access through a single approved method reduces attack surface and speeds repairs.[1]
  • Instrument selection and commissioning must account for internal tank obstructions: non‑contact radar can fail in obstructed tanks, creating overfill or underfill risk and potential unplanned downtime — factor testing and positioning into scope.[2]
  • Network and field‑device options are shifting: certified bus technologies, industrial VPN gateways and 5G switches give more secure connectivity choices but create integration and support dependencies.[3]
  • These technical shifts have direct contract implications: require defined remote‑access methods, ownership of device credentials, and commissioning evidence in LTSAs to avoid hidden OPEX or access disputes.[1]
  • Evidence is practical and actionable rather than speculative: articles provide vendor‑level options and field constraints to update RFx, acceptance tests, and supplier checklists — not a market‑wide shock.[2][1]

What changed since last run

  • Added explicit OT remote‑access governance as a procurement priority based on new guidance about tool sprawl and third‑party attack surface (Article 3).
  • Added a procurement note on non‑contact radar limitations in obstructed tanks that affects instrumentation selection and commissioning scopes (Article 1).
  • Flagged new secure industrial networking and gateway products that can be specified in RFx/contract terms to reduce remote access exposure (Article 5).

Key facts

  • Most organisations have multiple remote access tools
  • High proportion of cyber incidents involve third‑party access
  • Maturity model spans do‑nothing to full centralised control
  • Non‑contacting radar provides top‑down measurement with low maintenance when suitable
  • Obstructions like agitators and coils create false echoes that can cause overfill or underfill
  • Remedial interventions are disruptive and rarely justified unless recurring problems are proven

Why it matters

Centralise and standardise third‑party remote access: tool sprawl increases cyber risk and slows troubleshooting; gating vendor access through a single approved method reduces attack surface and speeds repairs. Instrument selection and commissioning must account for internal tank obstructions: non‑contact radar can fail in obstructed tanks, creating overfill or underfill risk and potential unplanned downtime — factor testing and positioning into scope. Network and field‑device options are shifting: certified bus technologies, industrial VPN gateways and 5G switches give more secure connectivity choices but create integration and support dependencies. These technical shifts have direct contract implications: require defined remote‑access methods, ownership of device credentials, and commissioning evidence in LTSAs to avoid hidden OPEX or access disputes

Cost / money

  • Expect negotiation leverage pressure from suppliers who insist on their preferred remote tools or proprietary gateways; without contract rules, buyers may pay recurring access or licence pass‑throughs.[1]
  • Selecting non‑contact radar as default can reduce maintenance spend where it works, but in obstructed tanks it may drive retrofit costs or commissioning interventions if false echoes occur.[2]

Supplier / commercial

  • Suppliers with approved secure remote‑access methods (or gateway products) will gain shortlist advantage; require proof of compatibility with the buyer’s centralised tool in RFx to avoid late exclusions.[1]
  • Vendors supplying level measurement may push for scope limits or change orders where tank obstructions raise measurement uncertainty — contractually capture acceptance tests and mobilisation assumptions.[2]

Safety / operations

  • Inaccurate level readings from false radar echoes create overfill, spill and pump dry risks; include witness tests and staged acceptance to protect safety and custody transfer accuracy.[2]
  • Uncontrolled third‑party remote sessions expand the cyber attack surface and can delay incident response; require logging, session control and escalation paths in LTSA/SLA language.[1][3]

What to watch

  • Watch suppliers to propose their own VPNs or access appliances as the preferred route; without contractual limits this shifts operational dependency and support costs to the buyer.[1]
  • Watch for engineering proposals that default to non‑contact radar without site echo‑validation; this saves CAPEX on paper but may create OPEX or retrofit risk on obstructed tanks.[2]

How to centralise remote access: securing all access to your OT systems

Signal strongSource-grounded
Source notes [1]Read source

What happened

The piece recommends centralising remote access to operational technology to reduce tool sprawl and the third‑party attack surface. It shows many organisations use multiple remote tools and links that tool sprawl to increased cyber incidents and slower governance. Watch whether procurement can mandate a single approved gateway or must manage supplier exceptions

Buyer takeaway

Require a central approved remote‑access method in RFx/LTSA or capture exceptions explicitly; otherwise suppliers will introduce tool and support costs

Cost / money

Undefined remote access can create recurring licence or support pass‑throughs; lock cost treatment in contract templates

Supplier / commercial

Suppliers with compatible gateway solutions will win on fit‑to‑scope; mandate proof of compatibility to avoid late change orders

Safety / operations

Controlled access improves incident traceability and response; include session logging and escalation paths in acceptance criteria

What to watch

Suppliers may resist single‑tool rules and propose their own appliances; require documented exceptions and sunset clauses

Key facts

  • Most organisations have multiple remote access tools
  • High proportion of cyber incidents involve third‑party access
  • Maturity model spans do‑nothing to full centralised control

Source excerpts

Level 1: First-party access — Internal engineers use a centralised remote access tool
” Binding Agreements: “Remote Access is built into our contract
Tool sprawl like this translates to an expanded attack surface, so it’s no coincidence that 82% of organisations have experienced at least one cyber attack related to third-party access. And that’s only breaches from third-party remote access — not including internal engineers remotely accessing critical devices
Story 2Processonline

Ensuring reliable level measurement in tanks with internal obstructions

Signal strongSource-grounded
Source notes [2]Read source

What happened

The article explains that non‑contacting radar level transmitters can misread tanks with internal obstacles because false echoes confuse the sensor. It stresses that positioning, technology choice or additional measures are needed for reliable readings and that remedial work is disruptive and costly. Watch for site‑specific echo validation requirements prior to awarding instrumentation work

Buyer takeaway

Mandate site echo‑validation and transmitter positioning as part of acceptance; include alternate tech options in the RFx for obstructed tanks

Cost / money

Defaulting to radar without validation risks unplanned retrofit or increased commissioning charges; capture mobilisation and remediation exposure in scopes

Supplier / commercial

Vendors may quote narrow‑validity offers for complex tanks; require detailed test evidence and fixed acceptance gates to reduce dispute risk

Safety / operations

False echoes can lead to spills or pump damage; staged acceptance and witness tests protect safety and custody transfer accuracy

What to watch

Be wary of proposals that downplay echo testing to save CAPEX; these often shift costs into OPEX and change orders later

Key facts

  • Non‑contacting radar provides top‑down measurement with low maintenance when suitable
  • Obstructions like agitators and coils create false echoes that can cause overfill or underfill
  • Remedial interventions are disruptive and rarely justified unless recurring problems are proven

Source excerpts

Figure 2: Internal equipment can make it challenging for a non-contacting radar level transmitter to differentiate the true surface echo from false echoes coming from obstructions. Strategies for mitigating false echoes While tanks containing internal structures present clear challenges for non-contacting radar level transmitters, a number of strategies can help to reduce or eliminate the impact of false echoes
The result is a more stable, accurate and dependable level measurement
Level data underpins effective process control, optimised inventory management and precise custody transfer — all of which directly influence productivity and profitability. In addition, level measurement is central to critical safety applications such as overfill prevention
