Your hardware hit end of support. Here’s what actually matters.
You already know what end-of-service-life means. What you need now is the part nobody spells out: exactly what you’re exposed to, what third-party maintenance really covers and what it doesn’t, and a straight way to decide box by box. EOSL.ai sells nothing here — this is the neutral version.
What running past EOSL actually exposes you to
The vendor stops shipping firmware and security (PSIRT) advisories. New CVEs in the platform go unpatched forever, and attackers actively scan for known end-of-life network gear because it’s a dependable foothold. TPM does not fix this — only the OEM ships firmware.
Unsupported components can create audit and control-review issues — NIST SP 800-53 SA-22 specifically covers them, and PCI DSS, HIPAA and ISO/IEC 27001 all expect firmware updates, replacement parts, maintenance contracts, or a documented exception. Be ready with a compensating control or a remediation date.
Past EOSL the OEM won’t RMA a failed unit or take a Sev-1 case. A dead power supply or line card becomes an outage measured by how fast you can find a used part — unless spares or TPM are arranged first.
Insurers and customer security questionnaires increasingly ask whether you run unsupported infrastructure. Undisclosed EOL gear can complicate a claim or breach a security clause. Know what you’re running before you’re asked — check your stack.
Third-party maintenance, without the spin
TPM is the most common path past EOSL — and the most misunderstood. The honest version: it’s excellent for hardware risk and does nothing for software/security risk.
- Hardware break/fix and replacement parts, often forward-stocked near your site
- On-site engineers and 24×7 SLAs — frequently better than the OEM’s last offering
- Multi-vendor gear consolidated under one contract and one SLA
- Usually well below the OEM’s final renewal price
- Support for gear the OEM won’t sell a contract for at all
- Firmware / OS updates and security patches — only the OEM ships these
- New software features and release trains
- Vendor TAC for software bugs and design help
- Anything that closes a CVE on an internet-facing device
- The compliance gap on its own — you still document a control
How to vet a TPM provider — the questions that separate good from bad
- Where are spare parts stocked relative to this site, and what’s the guaranteed on-site part time?
- Do they forward-stock a spare for your exact model, or source on demand from brokers when it fails?
- What’s the real SLA — 4-hour on-site vs next-business-day — and what’s the penalty if they miss it?
- Are their engineers certified on this platform, and do they diagnose or just swap parts?
- Can they supply firmware you’re already entitled to — and are they upfront that new firmware still requires the OEM?
- References running the same gear, and is it month-to-month or a multi-year lock-in?
The established providers in this market include Park Place Technologies, Service Express, Curvature, Procurri and Evernex, among others. EOSL.ai has no affiliation with any of them and earns nothing from naming them — get competing quotes and hold each to the questions above.
The other paths, and when each fits
Some vendors sell time-limited extended or custom support past standard EOSL, at a premium and not for every model. Worth it when a rule specifically requires the original vendor, or a migration is scheduled and close.
Move to a supported platform. Every past-EOSL model page here names the vendor’s recommended successor when one was published — and links to that successor’s own lifecycle page. Browse them on replacements.
Buy spares now, while units still circulate, and self-maintain — pairs well with TPM. Best for medium-criticality gear where a same-day part matters more than a contract.
A deliberate decision, not a default: document the risk, harden backups and monitoring, and retire on your terms. Only for non-critical, easily-replaced, well-segmented gear.
Decide box by box, not fleet-wide
The right path is a function of two things — how critical the box is, and how exposed it is. A rough map:
| Business criticality | Internet-facing or sensitive data | Internal / segmented |
|---|---|---|
| Mission-critical | Migrate now. The security exposure outweighs the cost; use TPM only as a short bridge to a scheduled cutover. | TPM for hardware cover + a funded migration plan. Segment and monitor in the meantime. |
| Important | Migrate or replace this cycle; if truly not possible, TPM + tighten segmentation and compensating controls. | TPM or spares to defer the refresh; document the compliance exception with a review date. |
| Low / replaceable | Replace or retire — don’t run unsupported internet-facing gear for low value. | Spares or run-to-failure with the risk documented. |

Support-options questions
Does third-party maintenance patch security vulnerabilities?
No — this is the most common misconception. A TPM provider covers hardware: break/fix, replacement parts, on-site engineers. Firmware and security patches only ever come from the OEM, and the OEM stops shipping them at end of service life. So on an internet-facing or sensitive device, TPM keeps the box running but does not close the growing gap of unpatched CVEs. Weigh that separately from the hardware-failure risk.
How much cheaper is TPM than the OEM?
Independent maintenance is typically well below the OEM's last renewal quote, but the real number depends on the model, the SLA and the provider — get two or three competing quotes rather than trusting a headline percentage. The bigger lever is often consolidating multi-vendor gear onto one TPM contract with a single SLA.
Is running end-of-life hardware a compliance problem?
It can create audit and control-review issues. NIST SP 800-53 SA-22 specifically addresses unsupported components (and alternative support sources like third-party maintenance), and frameworks such as PCI DSS, HIPAA and ISO/IEC 27001 generally expect that firmware/security updates, replacement parts and maintenance contracts are available — or that there's a documented exception with a compensating control. "It still works" is rarely enough on its own; have a remediation date or a documented control ready. See how EOSL.ai maps to these on the <a href="/standards/">standards page</a>.
When is it worth migrating instead of maintaining?
When the platform is strategic, the box is a performance bottleneck, or it's internet-facing where the unpatched-firmware exposure is unacceptable. If migration is already scheduled and close, TPM is a sensible bridge to the cutover. Every past-EOSL model page here lists the vendor's recommended successor when one was published — and links to that successor's own lifecycle page.
Does EOSL.ai sell hardware or maintenance?
No. EOSL.ai does not sell hardware or maintenance directly, and the provider names on this page are the market landscape, not endorsements. If we ever introduce referral partners or paid placements, they will be clearly disclosed and will never change a source-backed date. If you ask for help we reply with lifecycle detail on your specific hardware.
