Sectigo Certificate Manager Alternatives
A lot of people have the same phone plan they got at university. Not because it's the best plan. Not because they've shopped around. Because switching feels like work, the bill is auto-paid, and on most days they don't think about it. The plan does what it needs to do. The fact that it's been a little overpriced for several years now is the kind of thing you'd fix on a Saturday afternoon, but most Saturday afternoons are claimed by something else.
A lot of organisations use Sectigo Certificate Manager for similar reasons.
It works. It does what it needs to do. It came bundled with the Sectigo certs you bought when you were starting out. Switching feels like work. The renewal bill is auto-paid. On most days, nobody thinks about it.
Sectigo Certificate Manager is a fine product for its category. This page is for teams who are starting to wonder whether the category still fits, what the alternatives look like, and how to think about the switching cost.
When Sectigo Certificate Manager is the right call
You should keep using Sectigo if:
- You buy most of your certs from Sectigo and the bundle pricing works for you. Your cert estate is primarily TLS, with renewal handled by Sectigo's automation. Your team is small enough that one vendor for issuance + management is genuinely simpler. The tool gives you visibility you'd otherwise have to build.
If two or more of these apply, this page isn't about switching - it's just hygiene.
The "I've had this plan since university" signal
A specific test: when was the last time anyone on your team actively chose Sectigo as a cert manager? Not chose Sectigo certs - chose Sectigo Certificate Manager?
For many organisations, the answer is "we never really chose it, it came with the certs." That's the phone-plan signal. It doesn't mean the tool is wrong - it means the relationship is unexamined. An unexamined vendor relationship is sometimes fine and sometimes the source of accumulated tax that nobody's accounting for.
If you can't remember the last evaluation, the next evaluation is overdue.
When the alternatives are worth looking at
Sectigo Certificate Manager starts to feel like a constraint when:
- Your cert estate now includes certs from multiple CAs (Let's Encrypt for some, AWS ACM for others, internal CAs for service mesh). Sectigo's tool is designed around Sectigo certs and treats others as second-class. You're paying for management as part of the cert bundle, but you don't use most of the management features. The dashboard feels stuck in an earlier UI generation, and small daily friction adds up. You want monitoring features (chain validation, cipher checks, vulnerability scanning) that Sectigo's tool doesn't emphasise. Compliance audits now require evidence that Sectigo's reports don't cleanly produce.
Any of these is a signal that the bundle has stopped fitting. The fact that switching feels like work doesn't make the constraint less real.
The alternatives
TLS Radar. Disclosure: this is us. External monitoring for TLS certs from any CA - Sectigo, DigiCert, Let's Encrypt, AWS, internal - without bundling issuance or management. We check expiry, chain validity, cipher suites, hostname matches, and known vulnerabilities. The 30-day free trial covers three domains. Business at $199.99/month. Best for teams that want focused monitoring and have decoupled (or are decoupling) cert management from CA choice.
DigiCert CertCentral. The other big CA-bundled option. Same structural position as Sectigo - works best if you buy from DigiCert. See our DigiCert alternatives page for the same-but-different version of this conversation.
Keyfactor Command. Enterprise lifecycle management across any CA. Significant step up in feature scope and price. Worth considering if your situation is "we want to centralise cert lifecycle, not just management."
Venafi TLS Protect / AppViewX. Same category as Keyfactor. Enterprise-tier. Same caveats.
Red Sift Certificates. Security-led monitoring with a broader posture focus. Bundles with email security and brand monitoring; worth considering if your team's work spans those areas.
Keychest. Smaller and cheaper than the enterprise options. Good fit if you want focused monitoring at a lower price point.
AWS Certificate Manager, Cloudflare-managed certs. Free for their respective platforms. Doesn't cross platforms, but useful where they apply.
Build it yourself. Some teams do. The costs come due eventually - see Build vs. Buy (an earlier piece) for the honest take.
The switching cost question
For Sectigo specifically, the switching cost has two parts.
The tool side. Moving from Sectigo Certificate Manager to a different monitoring or management tool is a week of part-time work. Export the cert list, import into the new tool, point alerting at it, update dashboards.
The CA side. If you also want to move away from Sectigo as a CA, that's a separate, longer project. Each cert needs to be reissued from the new CA on its next renewal. This takes a year or more depending on cert validity. You don't have to do both at once - you can switch cert managers and keep buying certs from Sectigo, or switch CAs and keep using Sectigo's manager. Decoupling these decisions is itself a useful step.
The tool-side switching cost is small enough that "we've had this plan since university" stops being a strong defence once you actually count the hours.
How to choose
Three questions matter.
One: do you want to keep buying certs from Sectigo? If yes - Sectigo Certificate Manager is at least a reasonable default. Re-evaluate features against what the bundle gives you. If no - you have more room to choose a CA-neutral tool.
Two: do you have certs from multiple CAs already? If yes - you almost certainly want CA-neutral. Sectigo's tool will treat other CAs' certs as second-class. If no - bundled tools can work, but watch for the moment when this changes.
Three: are you a monitoring problem, a lifecycle problem, or both? Monitoring = TLS Radar, Keychest, Red Sift. Lifecycle = Keyfactor, AppViewX. Both = enterprise platforms or a focused monitor + decent automation.
A small bias to declare
We built TLS Radar to be the focused monitoring option for teams who are decoupling cert management from CA choice. Sectigo's tool is reasonable if the bundle still fits. If you're at the "haven't actively evaluated in five years" phase, the free tier of TLS Radar is the cheapest way to see what a focused tool looks like. If it doesn't fit, you've lost an afternoon.
