octoplant vs Software Defined Automation (SDA): On-Premises Breadth or Industrial DevOps

The octoplant vs Software Defined Automation question is a comparison between two different starting points. octoplant, from AMDT, starts from the installed base: back up and compare what is running across a wide range of devices, mainly on-premises. Software Defined Automation (SDA) starts from the engineer’s workflow: “Industrial DevOps for automation engineers”, delivered through the browser from a cloud platform, with an on-premises option (softwaredefinedautomation.io). They overlap on backup, version control and now vulnerability monitoring, and the overlap is growing: SDA added check-in and check-out in 2026 and demonstrated an importer for octoplant history. This page compares them on public facts as of October 2026 and says where each fits. It names no winner, because that depends on the plant.

octoplant vs Software Defined Automation: two starting points

SDA: the engineering platform. SDA describes itself as “one system of record for the intended and the actual state of your factory”, across every controller and every vendor (SDA), and in September 2026 relaunched that idea as a “State Layer for Physical AI” (SDA). Its service list, as of October 2026:

• Automated backup and version control
• Browser-based engineering, plus VS Code integration
• Secure remote access
• Vault and audit trail
• Firmware Vulnerability Monitoring
• Factory Agent and Factory Operator (AI and operations features)
• A Local Client for check-out, check-in and offline work, launched in beta at Automate 2026 (SDA)

Coverage is published. SDA’s documentation lists, by IDE version, Siemens STEP 7 and TIA Portal (including WinCC), Rockwell RSLogix 5000 and Studio 5000, Beckhoff TwinCAT, B&R Automation Studio, CODESYS, Bosch Rexroth ctrlX, Mitsubishi GX Works, Schneider Control Expert, WAGO, SEW-EURODRIVE drive software, KUKA WorkVisual and COPA-DATA zenon. Backup is not ticked for every entry, so read the columns, not the vendor names. At Hannover Messe and Automate 2026 it showed AI-assisted multi-vendor code analysis, firmware vulnerability management and Siemens Sinumerik CNC backup (Automate.org).

octoplant: the installed-base platform. AMDT describes octoplant as a platform that “automatically backs up, versions, and recovers the configurations of industrial devices… across all major automation vendors” (amdt.com). AMDT states support for 180+ device types from 160+ vendors, with examples spanning PLCs, robots, CNC, drives, SCADA and HMI, switches and firewalls, PC images and unnetworked machines. octovision adds multi-site inventory, CVE matching and lifecycle data built from octoplant’s device data.

What the named customers say about each. AMDT’s public case studies lean toward scale and recovery. Bosch built B4M, a “Backup for Manufacturing” service for its locations worldwide, on octoplant (AMDT). At thyssenkrupp Presta’s 24 production sites, AMDT reports that “restarts that used to take several hours can now be realised in just a few minutes” (AMDT). SDA’s list leans toward large European manufacturers in automotive, pharma and chemicals, with BMW Group, Boehringer Ingelheim and Henkel on its site, and its September 2026 announcement adds Henkel “across its factory networks”, PepsiCo’s brownfield plants and Electric Hydrogen’s new electrolyzer factory. SDA also reports more than 23,000 code versions under management and fivefold growth in managed controllers since January 2026 (SDA). Both sides’ figures are vendor-published and self-reported.

One overlap is worth noting: Egger appears on both sides, in AMDT’s case study titles and on SDA’s customer list. Large manufacturers often run different tools at different sites, or evaluate more than one. A logo is not proof of a plant-wide standard.

Virtual PLCs change what has to be backed up

SDA has marketed this as a point of difference, and it is worth understanding in plant terms. Its homepage still describes managing “Virtual PLCs running on commercial off-the-shelf IT servers”, although as of October 2026 its dedicated virtual PLC page redirects elsewhere, so ask what ships today. A physical PLC holds logic, firmware and a hardware configuration. A virtual PLC runs as software on an IT server, so its recoverable state spreads across more layers.

For a plant planning virtual PLCs, that is a reason to put the question to SDA first, and to ask AMDT and every other vendor for its virtual PLC roadmap. For a plant whose next ten years are physical controllers, robots and drives, it is not yet a deciding factor.

Where each fits

SDA tends to fit when:

• Engineering is moving to the browser or VS Code, with modern software practices
• Virtual PLCs on IT servers are planned or already running
• Secure remote access and engineering are wanted on one platform
• Cloud hosting with an on-site gateway is acceptable, or the on-premises edition fits
• The team wants a published per-device pricing structure and a public vendor matrix

octoplant tends to fit when:

• The estate is broad and old: many vendors, robots, CNC, drives, HMIs, switches and unnetworked machines
• On-premises is the default, not an edition to negotiate
• The plant runs versiondog or AutoSave, where octoplant is the direct successor
• The priority is recovery of what is running today, with audit evidence

A plant scenario (illustrative). A pharma site plans to move two packaging lines onto virtual PLCs in 2028, while its formulation area keeps physical controllers, robots and a validated SCADA system for a decade. The new lines are a natural SDA pilot. The validated estate needs an audit trail and change control that quality already accepts. Running two tools for two different futures can be the right answer, if each has a defined scope and one owner.

Questions to ask both vendors

1. Which of our controllers, robots, drives and CNC machines do you support today, in writing?
2. Where do backups, credentials and audit logs live, and can that be entirely on our premises?
3. How long does a restore of one controller take without the engineering laptop that last touched it?
4. Which virtual PLC runtimes do you support now, and which are on the roadmap?
5. What does the AI feature send off site, if anything?

Where it gets hard

Remote access is a security decision, not a feature. A platform that combines engineering and remote access into OT reaches far. Review the access path with whoever owns OT security before any pilot, and see our guide to OT network segmentation.

Vulnerability data depends on the source. octovision matches CVEs against firmware and software data held in octoplant; see Vulnerability Management. SDA states that its service can “proactively scan devices for known threats” (SDA). Ask both how firmware is identified, which CVE sources are used and how false positives are handled.

Coverage beyond PLCs. SDA’s public matrix is PLC-led but includes SEW drive software, KUKA WorkVisual and zenon, with Sinumerik CNC added in 2026 and robots, IPCs and switches named on its pricing page. If robots, drives and network devices carry real recovery risk, test them explicitly. octoplant’s breadth is AMDT’s claim, and also needs testing on your devices; see Robots, CNC and Drives.

Compliance claims need reading closely. SDA states that it is ISO 27001:2022 certified and SOC 2 Type II attested, and lists FDA 21 CFR Part 11 and NIS2 as frameworks it helps customers meet (SDA). AMDT’s Trust Center lists ISO/IEC 27001:2022, ISO 9001 and TISAX (amdt.com). The first two kinds are certifications of the vendor; the frameworks are obligations on the plant that a product can only support.

Migration claims need a test. SDA’s “Octoplant Importer” (SDA) lowers the cost of leaving octoplant if it carries history faithfully. Run it on a copy of a real archive before counting on it.

Vendor scale. We found no SDA funding after the 2022 seed. AMDT is an established vendor with a large installed base. Neither fact decides the evaluation, but both belong in a ten-year view.

An independent owner’s engineer can frame that evaluation. Compare also octoplant vs Copia, or return to octoplant Alternatives.
