ManageEngine ServiceDesk Plus vs BMC Helix vs ServiceNow for on-prem-heavy enterprises
Short answer
All three can run in your own data centre, which surprises people who think of ServiceNow and Helix as SaaS only. They do it in very different ways. ManageEngine ServiceDesk Plus is the conventional on-premises product with a published price list: on-prem Enterprise, the edition with change, problem, CMDB and projects, is US$1,195 a year for 2 technicians and 250 IT assets, rising to US$21,595 for 50 technicians and US$35,995 for 200 (about £886.76, £16,024.78 and £26,710.45, indicative; ManageEngine shows no GBP). BMC Helix Service Management has a documented on-premises container deployment on Kubernetes or OpenShift, including HelixGPT, but Helix does not support hybrid splits, for example Service Management on-prem with Helix AIOps in SaaS. ServiceNow offers Self-Hosted (“formerly known as on-premise”): the same application software, run on hardware, databases and networks you operate, with some features unavailable because they depend on ServiceNow-hosted services. Helix and ServiceNow are quote-only; we do not estimate them. Our view: SDP is the default for on-prem-first IT departments that want to run the tool themselves. Helix suits Remedy estates that must stay on-prem. ServiceNow Self-Hosted is for sovereignty-bound organisations that need the full platform and can staff its operation.

Who this guide is for
This guide is for IT leaders at enterprises where “cloud first” has limits: defence suppliers, regulated banks, public bodies, telecoms, manufacturers with plant networks, and any organisation whose security team has said some service-management data must stay on infrastructure it controls, or at least inside one country. If your service desk runs on-premises today, or a regulator, customer contract or air-gapped network will keep it there, this comparison is for you.
We compare three products that all have an answer to that requirement: ManageEngine ServiceDesk Plus (SDP), BMC Helix (sold by Helix, now independent of BMC Software after Montagu completed the carve-out on 2 October 2026, per the Montagu announcement), and ServiceNow. Sources, all checked on Nov 9, 2026: the ManageEngine ServiceDesk Plus pricing page, the ServiceDesk Plus Cloud data centre list and ServiceDesk Plus Cloud data centre feature comparison; the BMC Helix Service Management on-premises deployment overview, BMC Helix Service Management on-premises system requirements and BMC Helix service locations page; and the ServiceNow product launch post on its Self-Hosted offering and the ServiceNow ITSM pricing page. Opinions are ours and labelled as such.
Quote-only means quote-only
BMC Helix and ServiceNow do not publish list prices. Helix uses a Helix pricing request form; ServiceNow asks for a custom quote. We do not estimate either in USD or GBP, and we do not guess at self-hosted uplifts or workshop fees.
Deployment options, from vendor pages
| ServiceDesk Plus | BMC Helix Service Management | ServiceNow | |
|---|---|---|---|
| On-premises / self-hosted | Yes: on-premises edition, priced separately from cloud | Yes: container deployment of BMC Helix Innovation Suite and Service Management applications in your environment | Yes: Self-Hosted, “formerly known as ‘on-premise’”, customer- or partner-operated |
| Vendor SaaS | Yes: ServiceDesk Plus Cloud in 9 data centres (US, EU, India, China, Australia, Japan, Canada, UK, Saudi Arabia) | Yes: Helix SaaS from regional service locations including EU, UK, US, Canada, Asia Pacific, South Africa, UAE, Saudi Arabia and a German Regulated Cloud | Yes: ServiceNow commercial cloud (region details are not on the pages we checked) |
| Who runs the infrastructure on-prem | You | You: Kubernetes or OpenShift, plus database (Microsoft SQL Server, Oracle or PostgreSQL are documented setup paths) | You or a partner: hardware, database, load balancers, networking and operating system |
| Hybrid splits | Not applicable in the same sense; separate products per deployment | “Hybrid deployments of BMC Helix Service Management and BMC Helix IT Operations Management are not supported”; no mixed on-prem and SaaS Service Management instances | Not described on the pages we checked |
| Feature parity with SaaS | Cloud feature availability varies by data centre (see below) | On-prem FULL mode includes ITSM Service Desk, Asset, Knowledge, Smart IT, Digital Workplace, HelixGPT and more; Helix Virtual Agent and Helix Integration Service are not available on-prem | “Not all features are at parity with our commercial release”; some features unavailable because they depend on ServiceNow-hosted services |
ServiceDesk Plus: on-prem is a first-class edition
ManageEngine treats on-premises as a normal way to buy SDP, with its own price table and a 30-day trial for both cloud and on-prem. You install it, patch it and back it up. For an IT department that already runs Windows or Linux servers and a database, this is the least exotic option of the three, and the only one with published prices.
BMC Helix: containers on your Kubernetes
Helix’s on-prem story is a containerised deployment that Helix describes as “an automated process that significantly reduces deployment complexity” compared with the older server-based installers. It still assumes real platform skills: Day 0 planning includes sizing the container environment and setting up a Kubernetes cluster; Day 1 includes a Harbor repository synchronised with BMC’s Docker Trusted Registry, database preparation, the BMC Helix Deployment Engine and a Jenkins pipeline. Helix also documents migrating Remedy on-premises (20.02 and earlier) to on-prem Helix Service Management by fresh installation and data migration with BMC Helix Data Manager. That is why Helix is the natural on-prem path for existing Remedy estates.
ServiceNow Self-Hosted: the same software, your operations
ServiceNow’s product-launch post describes Self-Hosted as delivering “the same application software that runs in our commercial cloud, but deployed and operated within your own infrastructure.” ServiceNow supplies the software, deployment guidance, upgrade packages and support; you own the hardware, database, load balancers, networking and OS. ServiceNow says the offering serves organisations across defence, government, banking, telecom and technology, and that customers “should expect to purchase a workshop” covering architecture, sizing, database selection and operational readiness. The path starts with your account team.
What you give up when you self-host
Self-hosting always costs some convenience. The vendors are unusually specific about what.
| Product | Unavailable or limited when self-hosted (vendor statement) |
|---|---|
| ServiceNow Self-Hosted (Australia release highlights) | Not available: Instance Data Replication, Cloud Encryption (ServiceNow Vault), AI Gateway, Dynamic Translation, Workflow Data Fabric connectors (Zero Copy and External Content Connectors), Impact Instance Observer, ServiceNow IDE / developer sandboxes, Virtual Agent third-party integrations such as Teams and Slack. Instance Clone is listed as unavailable with a manual method available. Available: Now Assist, AI Agents and Knowledge Graph (Zurich onward), AI Search and Predictive Intelligence, RPA, Process Mining, Automation Center, field encryption, automated upgrades (internet-connected) and Store app downloads. |
| BMC Helix on-prem (FULL mode) | Not available on-prem: BMC Helix Virtual Agent and BMC Helix Integration Service. CORE mode (platform and CMDB only) is under controlled availability. |
| ServiceDesk Plus | The on-prem product is its own edition. The vendor’s data-centre comparison covers Cloud, and shows feature gaps by cloud region rather than for on-prem. |
For an on-prem-heavy enterprise the ServiceNow list matters most if you expected the Teams and Slack virtual agent experience, because that is on the unavailable list. For Helix, the missing Virtual Agent is the equivalent gap. Both are worth testing against the employee channel you plan to use.
AI when the data must stay in your environment
| ServiceDesk Plus | BMC Helix | ServiceNow Self-Hosted | |
|---|---|---|---|
| What the vendor says | “Predictive, generative, and conversational AI capabilities are available across all editions at no additional cost. Zia Agents are included in the Enterprise Edition.” | BMC HelixGPT is available in on-prem FULL mode (optional in CORE mode) | Generative AI is available for Self-Hosted customers across ITSM, CSM, ITOM, HRSD, SecOps, FSM, SPM and more |
| How the models run | Cloud data-centre table lists Zia (a Zoho-hosted LLM) by default, plus Azure OpenAI, ChatGPT, Claude and Google AI Studio integrations, varying by region | HelixGPT is bring-your-own LLM (documented on Helix subscriber pages, as covered in our Helix pricing guide) | ServiceNow’s production LLMs on customer-owned GPUs, or bring-your-own-key with Azure OpenAI, AWS Anthropic or Google Gemini; your own LLM with a more limited experience |
| Commercial note | No extra AI charge on the pricing page | Quote-only | Now Assist credits consumed under the same pricing model as commercial SaaS |
| Caveats | Several autonomous AI features (Zia Agent Studio, L1 ServiceDesk Specialist) are listed for US, EU, AU and IN cloud data centres but not UK | Confirm HelixGPT licensing in the quote | Self-hosted GenAI images are updated twice a year; data sharing is disabled by default; AI Agents from the Zurich release |
Two practical points. First, “AI on-prem” on ServiceNow means you provide GPU infrastructure or an approved cloud model key. That is a real procurement line item, not a checkbox. Second, if you are a UK organisation considering SDP Cloud rather than on-prem, read the ServiceDesk Plus Cloud data centre feature comparison carefully: on Nov 9, 2026 it showed Zia Agent Studio, the agent store, Request Context Assistant, L1 ServiceDesk Specialist, Helpdesk Coach and the KB Article Generator as not available in the UK data centre, and ManageEngine notes you can choose the EU data centre at sign-up instead.
Data residency if you do use the vendor cloud
Many “on-prem-heavy” enterprises end up with a mixed estate: production ITSM on-prem, a subsidiary or test instance in a vendor cloud. Residency then matters.
- BMC Helix SaaS: Helix says it “supports the data residency requirements of its customers through the initial selection of a service location. Once selected, data remains within the same country for that service.” It lists a UK customer region on Oracle Cloud Infrastructure, EU locations in Amsterdam and Frankfurt, and a German Regulated Cloud in Nuremberg. Exceptions to note: BMC Helix Knowledge Management by ComAround is only hosted in Azure in the Netherlands, and services using the Jitterbit platform “may have data processed outside of the country of the primary service location.”
- ServiceDesk Plus Cloud: nine data centres, each with its own domain and Zoho accounts server, including UK (servicedeskplus.uk) and EU (sdpondemand.manageengine.eu). Feature availability differs by data centre, as above.
- ServiceNow: the pages we checked today describe Self-Hosted in detail but do not list commercial cloud regions. Ask your account team, in writing, which data-centre pair will host your instance and where backups live.
Pricing: what is published and what is not (checked Nov 9, 2026)
Only ManageEngine publishes prices. The table below is the on-premises annual table from the ManageEngine ServiceDesk Plus pricing page (which says prices are “current as of September 2026 and are subject to change”). Standard covers the IT service desk; Professional adds asset management; Enterprise adds change, projects and the rest of the ITIL set with ITAM and CMDB. Prices are per year for the technician and IT-asset bundle shown; end users are not charged.
| On-prem bundle (per year) | Standard USD / GBP | Professional USD / GBP | Enterprise USD / GBP |
|---|---|---|---|
| 2 technicians, 250 IT assets | Free / Free | $495 / about £367.32 | $1,195 / about £886.76 |
| 5 technicians, 500 IT assets | Free / Free | $1,195 / about £886.76 | $2,995 / about £2,222.47 |
| 10 technicians, 500 IT assets | $1,195 / about £886.76 | $2,295 / about £1,703.03 | $5,995 / about £4,448.65 |
| 20 technicians, 500 IT assets (1,000 for Enterprise) | $2,395 / about £1,777.23 | $4,545 / about £3,372.66 | $10,795 / about £8,010.54 |
| 50 technicians, 1,000 IT assets (2,000 for Enterprise) | $4,795 / about £3,558.18 | $10,795 / about £8,010.54 | $21,595 / about £16,024.78 |
| 100 technicians, 1,000 IT assets (2,000 for Enterprise) | $8,395 / about £6,229.59 | $19,195 / about £14,243.84 | $29,995 / about £22,258.09 |
| 200 technicians, 1,000 IT assets (3,000 for Enterprise) | $11,995 / about £8,901.01 | $23,995 / about £17,805.73 | $35,995 / about £26,710.45 |
The same page gives cloud starting points: Standard free up to five technicians, then from $1,545 a year for 10 technicians (about £1,146.48); Professional from $645 a year (about £478.63) and Enterprise from $1,595 a year (about £1,183.59), each for two technicians and 250 assets. Technical support is included for paid customers (24x5, except public holidays); free-edition users can buy annual maintenance at $35 per technician (about £25.97). Indicative GBP conversions use the Bank of England daily spot rate (series XUDLUSS) of US$1.3476 per £1 for 5 Nov 2026, which was still the latest published figure when we re-checked the Bank of England series on Nov 9, 2026. They are not official UK prices: the vendor does not publish a GBP list price for these items, and your invoice currency, rate and VAT treatment may differ.
| Product | USD | GBP | How to get a number |
|---|---|---|---|
| BMC Helix Service Management (SaaS or on-prem) | Quote-only | Quote-only | Helix pricing request form; licensing is named or concurrent users (see our Helix pricing guide) |
| ServiceNow ITSM (cloud or Self-Hosted) | Quote-only | Quote-only | Account team; ITSM Foundation, Advanced and Prime packages; Self-Hosted adds an expected workshop purchase |
Our opinion on the comparison: for a 50 to 200 technician on-prem desk, SDP’s published Enterprise prices are a small fraction of what most enterprises budget for the other two. That is not a like-for-like comparison of capability, but it explains why SDP is so often the incumbent in on-prem estates. The honest question is whether you need what Helix or ServiceNow add, not whether SDP is cheaper.
Who has to run it: the hidden cost of on-prem
| Operational job | ServiceDesk Plus on-prem | BMC Helix on-prem | ServiceNow Self-Hosted |
|---|---|---|---|
| Platform skills needed | Application server, database, backups | Kubernetes or OpenShift, container registry, Jenkins pipeline, database | Full three-tier stack: load balancers, application servers, database tier |
| Upgrades | You apply vendor releases | In-place upgrade path documented | Upgrade packages from ServiceNow; family release files available the same day as cloud |
| Disaster recovery | Yours | Yours | Reference architectures supplied; operation is yours |
| Typical owner | The IT infrastructure team | A platform team with container experience | A dedicated platform team or a partner |
This is where on-prem decisions are really made. A ServiceNow Self-Hosted estate needs a team that can operate an enterprise platform. A Helix on-prem estate needs container skills. SDP needs the server team you already have. If your organisation cannot staff the operations column, the cheaper or simpler tool will serve you better than the stronger one.
Best for, and wrong choice when
ServiceDesk Plus is best for
On-prem-first IT departments of up to a few hundred technicians that want ITIL processes, asset management and CMDB on servers they already run, with published prices and AI included in every edition.
ServiceDesk Plus is the wrong choice when
You need one platform for large-scale, cross-department workflow and deep CMDB-driven operations, or your governance depends on capabilities only Helix or ServiceNow provide.
BMC Helix is best for
Remedy estates that must stay on-premises, have a container platform team, and want a documented migration path with BMC Helix Data Manager, plus HelixGPT under their own control.
BMC Helix is the wrong choice when
You want a hybrid split between on-prem Service Management and SaaS AIOps, which Helix says is not supported, or you need the Helix Virtual Agent on-prem.
ServiceNow Self-Hosted is best for
Sovereignty-bound or air-gapped organisations that need the full ServiceNow platform, including generative AI on their own GPUs or approved model keys, and can staff platform operations.
ServiceNow Self-Hosted is the wrong choice when
The main reason is cost control, or you rely on Teams or Slack virtual agent integrations, instance data replication or Vault encryption, which ServiceNow lists as unavailable.
If you are on SDP and wondering whether to leave on-prem altogether, our ServiceDesk Plus to Freshservice or JSM migration guide covers that route. If Helix and ServiceNow are the shortlist in a SaaS context, see BMC Helix vs ServiceNow.
Frequently asked questions
Can ServiceNow be installed on-premises?
Yes, as ServiceNow Self-Hosted, which ServiceNow describes as its customer- or partner-operated deployment model “formerly known as on-premise”. You run the hardware, database, load balancers, networking and operating system; ServiceNow provides the software, upgrades and support. Some features are unavailable because they depend on ServiceNow-hosted services.
Can BMC Helix ITSM run on-premises?
Yes. Helix documents a container deployment of BMC Helix Innovation Suite and Service Management applications on Kubernetes or OpenShift, including ITSM Service Desk, Asset, Knowledge, Smart IT, Digital Workplace and HelixGPT in FULL mode. Helix Virtual Agent and Helix Integration Service are not available on-prem.
How much does ServiceDesk Plus on-premises cost?
On Nov 9, 2026, ManageEngine’s on-prem table listed Enterprise at $1,195 a year for 2 technicians and 250 IT assets, $21,595 for 50 technicians and $35,995 for 200 technicians (about £886.76, £16,024.78 and £26,710.45, indicative; no official GBP shown). Standard is free for up to five technicians.
How much do BMC Helix and ServiceNow cost on-prem?
Neither publishes prices. Helix uses a pricing request form and ServiceNow quotes through its account team; ServiceNow also says Self-Hosted customers should expect to buy a workshop. We do not estimate either.
Is generative AI available if we self-host?
On all three, with caveats. ManageEngine says predictive, generative and conversational AI are available in every SDP edition at no extra cost. Helix lists HelixGPT in on-prem FULL mode. ServiceNow says generative AI runs on Self-Hosted via its models on customer-owned GPUs or bring-your-own-key providers, with images updated twice a year.
Can we run BMC Helix Service Management on-prem and Helix AIOps in SaaS?
No. Helix states that hybrid deployments of Service Management and IT Operations Management are not supported, and that you cannot have one Service Management instance on-prem and another in SaaS.
Does ServiceDesk Plus Cloud have a UK data centre?
Yes, at servicedeskplus.uk. ManageEngine’s comparison shows some features, including several autonomous AI features, not yet available in the UK data centre, and says you can choose the EU data centre at sign-up.
Which is best for an on-prem-heavy enterprise?
It depends on who will run it. SDP fits teams that want a conventional on-prem product at published prices; Helix fits Remedy estates with container skills; ServiceNow Self-Hosted fits sovereignty-bound organisations that need the full platform and can operate it.
