OEM vs. TPM · the honest comparison

OEM maintenance vs. Third-Party Maintenance

Is your vendor maintenance contract expiring or your hardware reaching EOSL? Here's the direct comparison of OEM maintenance and vendor-independent third-party maintenance (TPM) — cost, SLA, spare parts, compliance. Including the cases where OEM remains the right choice.

Briefly defined

OEM maintenance is maintenance directly from the manufacturer (e.g. HPE Foundation Care, Cisco SMARTnet, Dell ProSupport). Third-party maintenance (TPM) is vendor-independent maintenance by a specialist provider like TechCare — with original spare parts and equal or better SLAs, typically 30–70 % cheaper and also past End-of-Service-Life (EOSL).

Comparison at a glance

	OEM maintenance	Third-Party Maintenance (TechCare)
Cost	List price; post-EOSL custom support often 150–300 %	30–70 % below OEM — incl. past EOSL
SLA tiers	up to 24×7×4	equal or better tiers (up to 24×7×2)
Spare parts	OEM-new	OEM-original — own DACH depot + certified refurbishers
Past EOSL / End of Life	ends or expensive custom support	full maintenance, years past EOSL
Contract lock-in	often tied to bundles / refresh	flexible, no refresh pressure
Multi-vendor	one contract per vendor	one contract for all 28 vendors
Compliance	given	audit-ready: BAIT/MaRisk, DORA, NIS2, ISO 27001, TISAX
Software/firmware updates	included	hardware layer; OEM software subscription runs separately

When OEM, when TPM?

Stay with the OEM when hardware is brand-new under factory warranty, you actively use vendor-bound features/subscriptions, or a contract must legally stay with the manufacturer.

TPM wins past warranty and past EOSL, on multi-vendor fleets, under cost pressure and wherever there's no feature lock-in — at equal or better SLA. Unsure? The 3-question TPM check gives an honest read in 30 seconds.

Frequently asked

Do I lose the warranty if I switch to TPM?

No. Factory warranty on new hardware is unaffected as long as original spare parts are used. The TPM contract only takes full effect after warranty expiry. The misconception stems from US OEM marketing and doesn't match the legal reality in Germany.

Are the spare parts really original?

Yes — exclusively OEM-original parts from our own stocking hub, certified refurbishers and partly direct procurement. On request we provide chain-of-custody documentation (important for banks, government, critical infrastructure).

Is third-party maintenance compliant?

Yes. Compliance frameworks (DORA, NIS2, BAIT/MaRisk, ISO 27001, TISAX) require documented maintenance with defined SLAs — not an OEM contract. TechCare contracts are audit-ready; auditors typically accept them without discussion.

What does TPM cost versus the OEM renewal?

Rule of thumb: 30–70 % below OEM list price. Against post-EOSL OEM custom support (often 150–300 % of the regular level) the gap is largest. Concrete comparison figures within 48 hours after install-base review.

What about software and firmware updates?

TPM services the hardware layer. OEM firmware/microcode updates usually end at EOSL; an active software subscription (e.g. storage OS) continues separately via the vendor. On mature EOSL generations this is rarely a blocker in practice.

When is OEM maintenance the better choice?

On brand-new hardware under factory warranty, with actively-used vendor-bound cloud/feature subscriptions, or when a contract must legally stay with the OEM. In those cases we honestly recommend the OEM.
