Best Permit-to-Work and LOTO Software for 2026: An Independent Comparison

How We Evaluated

This numbered list is a use-case assignment drawn from public product pages and official documentation, not a ranking produced with the full method set in Reliable’s editorial policy. That policy also names feature evaluation, third-party user reviews, and consultation with maintenance professionals as ranking inputs. Those additional inputs were not compiled for these four products, so treat the order as use-case fit from vendor-stated capabilities, not as a full policy-method ranking. We read what each vendor states on its own pages and checked four things that matter on a plant floor: whether the permit and the isolation share one record or stay cross-referenced, whether a field user can work offline, whether SIMOPS or conflicting isolations are named, and whether a CMMS or EAM join is named on the public page.

Pricing is treated the same way: none of the four publish a list price, so we say so instead of guessing.

Reliable does not accept payment for rankings. Vendors may sponsor enhanced listings with additional detail, but editorial rankings are independent. Read our editorial policy.

4 Best Permit-to-Work and LOTO Software for 2026, Ranked by Use Case

1. Sphera Control of Work: Best for Multiphase Isolation Plans

Sphera positions Control of Work as a single shared view of a plant’s operational reality, covering work authorization, contractor compliance, and incident prevention inside the Sphera Process Safety Suite. Its Permit To Work component pulls permits, risk assessments, and isolations into one place, with pre-defined templates, real-time tracking, and dashboards, and it combines live information from permits, isolations, hazards, maintenance shifts, and SIMOPS. What sets it apart for complex shutdown and turnaround work is the Isolation Management page. It describes a single plan that encompasses multiphase isolation plans for different work stages, permits tied to specific isolation points, dependencies between those points, status tracking for each operational isolation point, and automatic alerts when an isolation is non-compliant or a conflict appears. For a plant sequencing isolations across stages of a large job, that structure is the reason to look here first.

Best for: Teams that need multiphase isolation plans, point dependencies, and conflict alerts inside a broader process-safety suite.

Starting price: Not published on the vendor page.

2. Enablon Control of Work: Best for AI-Assisted Drafting and P&ID Isolation

Enablon Control of Work, from Wolters Kluwer, unifies permit to work, isolation management, and risk assessments in one workflow, and it frames paper and spreadsheet systems as error-prone and short on visibility. Its distinguishing public claims are AI-powered permit drafting and isolation help built around P&IDs and smart iDiagram management, alongside real-time SIMOPS coordination and live hazard tracking. The page also names a mobile experience, though the pages used here do not state offline capability.

Best for: Teams that want AI-assisted permit drafting and diagram-based (P&ID) isolation, with SIMOPS coordination.

Starting price: Not published on the vendor page.

3. IntelliPERMIT: Best for Offline Mobile Permits

IntelliPERMIT, from Adapt IT Heavy Industries, is built for high-risk industries such as oil and gas, mining, power, and manufacturing, and it digitises and standardises control-of-work steps so that every job is authorised, hazards are identified, and controls are verified before work begins. Its electronic permit-to-work module replaces paper with a digital workflow and names hot work, confined space entry, working at heights, and non-routine maintenance. Its strength for field use is the mobile app, a companion to the main IntelliPERMIT application that is designed to work even without network connectivity on iOS and Android. In the field, users sign and view permits, conduct risk assessments, and verify isolation points, including by QR code or RFID scan, with updates flowing back to the permit record. Permit requests, creation, and the fuller approval workflow stay in the main application. IntelliPERMIT does note a limit on that offline mode: the mobile app keeps working with the most recent data when the connection drops, but because that can introduce inconsistencies and unsafe conditions, the vendor advises against using it where there is no signal for extended periods, and the app synchronises changes back to the main IntelliPERMIT server once it sees a signal again. Its Control of Work solution adds safety risk assessment, isolation management, and SIMOPS and conflict management. On the asset side, IntelliPERMIT states that it integrates with SAP PM, IBM Maximo, and other EAM systems to connect work orders, permits, and maintenance activities, with the integration options depending on your systems. It also names ArcGIS, Microsoft Project, access control, and LMS platforms including SuccessFactors, Moodle, and Bistrainer, running on-premises or in the cloud.

Best for: Field crews that need an offline-capable mobile companion on iOS and Android for signing permits and verifying isolations, with named plant integrations.

Starting price: Not published on the vendor page.

4. Prometheus ePAS: Best for EAM-Joined Permitting

Prometheus ePAS, the Electronic Permit Administration System, is a web-based integrated safe system of work with configurable workflows. Its defining feature for plants standardized on a major asset system is that it integrates permitting and safety directly with EAM, naming SAP, Oracle, and IBM Maximo. It handles hazard identification and risk assessment, including hot work permits with specialized HIRA and confined space permits that capture location, pre-entry atmospheric testing, and rescue-plan attachments. On the isolation side it covers templating, cross-referencing, isolation point validation, and tag printing, and it supports audits of safety documents and auditable permit practices across departments and sites. Its data sheet states real-time visibility into active work, and Prometheus states that the ePAS mobile application accepts inputs from the field whether online or offline. The pages used here do not name SIMOPS, so confirm that if it matters to you.

Best for: Plants that want permitting and isolation joined to a named EAM, whether SAP, Oracle, or IBM Maximo.

Starting price: Not published on the vendor page.

Comparison Table

How to Choose Permit-to-Work and LOTO Software

Lockout/tagout is the OSHA standard most directly tied to maintenance. In the finalized FY2025 Top 10, 1910.147 ranked 4th with 2,562 citations (Reliable’s OSHA most-cited maintenance violations). That is the backdrop for picking a tool. Five questions will narrow the field faster than a feature list.

1. Do the permit and the isolation share one record, or stay cross-referenced? Ask whether the permit and the isolation share one record, or whether they are separate documents that stay cross-referenced. HSE HSG253 states that isolation certificates can be used as part of a permit-to-work system where the isolation work is not detailed on the permit itself, and that certificates and permits should be cross-referenced. HSE HSG250 likewise says isolations should be clearly detailed on the permit or a supporting cross-referenced isolation certificate. The critical control is not removing an isolation too early, not blocking every permit close. Shared-record software can help; separate but cross-referenced permits and isolation certificates are also an accepted pattern.
2. Can your field users work offline? If crews sign permits or verify isolations in areas with weak signal, offline capability matters. Of the four here, IntelliPERMIT and Prometheus both state offline mobile use, while Enablon names a mobile experience without stating offline and the Sphera pages used here do not state it. Confirm the answer for any tool you shortlist.
3. Are SIMOPS or conflicting isolations named? When two jobs interact, or when one isolation conflicts with another, you want the tool to flag it rather than rely on someone catching it. Sphera, Enablon, and IntelliPERMIT name SIMOPS or conflict management on their public pages.
4. Does it name a join to your CMMS or EAM? A permit that connects to the work order and the asset record cuts double entry and keeps the isolation tied to the job. Prometheus names SAP, Oracle, and IBM Maximo. IntelliPERMIT names SAP PM, IBM Maximo, and other EAM systems.
5. Can you see a published price, or do you need a quote? None of the four publish a list price. Plan for a scoped quote based on your sites, users, and integrations, and ask what implementation and support cost on top of licensing.

Frequently Asked Questions

What is the best permit-to-work and LOTO software in 2026?

It depends on the job in front of you. For multiphase isolation plans inside a process-safety suite, Sphera Control of Work. For AI-assisted permit drafting and P&ID-based isolation, Enablon Control of Work. For an offline-capable mobile field companion on iOS and Android, IntelliPERMIT. For permitting joined to a named EAM such as SAP, Oracle, or IBM Maximo, Prometheus ePAS. Match the assignment to your site rather than looking for a single winner.

What is the difference between permit-to-work and LOTO?

Permit-to-work is the authorization workflow that controls non-routine, hazardous work. It documents the hazards, the controls, and who signed off before a job starts. Lockout/tagout is a specific hazardous-energy control. Under OSHA, lockout places a lockout device on an energy-isolating device so equipment cannot be operated until the device is removed, and tagout is a warning tag that does not provide the physical restraint of a lock. The four products here embed isolation or LOTO handling inside the permit workflow, so the two connect. They remain distinct: PTW is the authorization process, LOTO is one of the energy-control methods it enforces.

Does permit-to-work or LOTO software satisfy OSHA 1910.147?

No. OSHA 1910.147 requires an energy control program made up of energy control procedures, employee training, and periodic inspections. Software is not named anywhere in the standard, and no product satisfies it on its own. Energy control procedures must be documented except where all conditions of 1910.147(c)(4)(i)’s exception are met. Software can help you run and record the program, but the obligation stays with the employer.

Which of these tools states offline mobile use?

Of the four, IntelliPERMIT and Prometheus both state offline mobile use. IntelliPERMIT describes a mobile companion app designed to work even without network connectivity on iOS and Android, while advising against use where there is no signal for extended periods because the app runs on the most recent data and synchronises once a signal returns. Prometheus states that its ePAS mobile application accepts field inputs whether online or offline. Enablon names a mobile experience without stating offline. The Sphera pages used here do not state offline mobile use. Confirm current capability with each vendor before you rely on it.

Which tools name a CMMS or EAM join?

Prometheus ePAS names integration with SAP, Oracle, and IBM Maximo. IntelliPERMIT names SAP PM, IBM Maximo, and other EAM systems, plus access control and LMS platforms. Sphera names maintenance shifts rather than a specific EAM product. Enablon does not name a CMMS or EAM product on the pages used here.

Which tools name SIMOPS or conflict management?

Sphera, Enablon, and IntelliPERMIT name SIMOPS or conflict management on their public pages. The Prometheus pages used here do not name SIMOPS. If simultaneous operations are part of your risk picture, confirm the capability directly with each vendor.

If I use software, do I still need documented procedures?

Generally yes. OSHA 1910.147 requires energy control procedures, and those procedures must be documented except where all conditions of 1910.147(c)(4)(i)’s exception are met. Using software to build, store, or run your permits and isolations does not remove that requirement.

What do these platforms cost?

None of the four vendors publish a list price on the pages used here. Sphera, Enablon, IntelliPERMIT, and Prometheus all route pricing through a sales conversation, so plan to request a quote scoped to your sites, users, and integrations.
