Which certificate do I need?
Two quick questions get most people to the right type. Still unsure? Call us and we will tell you.
1. What do you need to secure?
- One website name (for example
www.example.com) → a single-domain certificate - Many subdomains of one name (
shop.,mail.,www.…) → one of our wildcard SSL certificates - Several different names (
example.comandexample.co.uk) → one of our multi-domain SSL certificates
2. Does your business need to be checked?
- No — just the padlock → domain validation (DV). Usually issued within about 10 minutes of validation, and the lowest cost: see our cheap SSL certificates.
- Yes — your organisation’s details verified and shown in the certificate → organisation validation (OV)
- Yes, the strictest check → extended validation (EV)
- OV and EV are our business SSL certificates; they usually take 2 to 3 working days.
ProntoSSL Automate: built for 47-day certificates
A new way of ordering SSL for anyone who would rather not replace certificates by hand. You connect your server once, using ACME or our install agent; Automate then orders, validates and installs each new certificate on schedule.
What changes with Automate
Same certificates either way| Ordering now | With Automate | |
|---|---|---|
| Proving ownership | You complete the email, DNS or file check | Completed for you at every new certificate |
| Installation | You install it on your server | Installed by ACME or the install agent |
| Replacing it | You reissue and reinstall before expiry | Starts automatically at 28 days remaining; you are emailed if it needs your help |
| Best for | A few certificates, looked after by hand | Several servers, or anyone who wants less to remember |
Automate looks after the certificate. You still keep the server reachable and the domain’s DNS correct, act on any alert we send, and look after the rest of your site’s security.

Why SSL is changing
The industry rules that set how long a certificate may last are tightening.
Shorter lifetimes
The maximum is 200 days now, 100 days from 15 March 2027 and 47 days from 15 March 2029. Replacing certificates goes from twice a year to roughly every six weeks. SSL certificate validity explained.
Reissues are free
Orders cover 12 months; each certificate within the order lasts up to 200 days. When one nears the end, you reissue it from your account — free and unlimited.
Expiry is the real risk
A lapsed certificate turns the padlock into a browser warning. We email reminders 30, 14, 7, 5, 3 and 1 day before expiry, so you can renew your SSL certificate in time.

Where do I order?
In our SSL certificate store on manual.prontossl.com, our new ordering website.
How quickly is a certificate issued?
Domain validation (DV) certificates are usually issued within about 10 minutes of validation. Organisation (OV) and extended (EV) validation usually take 2 to 3 working days.
How do renewals work?
Orders cover 12 months. We email reminders 30, 14, 7, 5, 3 and 1 day before the order expires, and you renew your SSL certificate from your account.
I am an existing customer — what has changed?
Only the website. Your account and certificates have moved across and keep working. Use “Forgot password” the first time you sign in.
Should I wait for Automate?
Not if you need a certificate now. Order today; you can move to Automate later if it suits you, or never — ordering on manual.prontossl.com carries on as it is.
Is an Automate certificate any different?
No. Same certification authorities and validation levels. Only who does the validating and installing changes.

Website statistics. We count visits with our own software on our own
server; nothing is shared with anyone else. For each page view we record the page, the
name of the site that linked to us, any campaign tags in the link (such as
utm_source), the type of device, the browser family (for example Chrome)
and the country the connection comes from. We do not store your IP address. To count
visitors without a cookie, we make a one-way code from your IP address, browser
details, the date and a secret value; it changes every day and cannot be turned back
into your address. Detailed records are kept for 13 months, then only daily totals.
Countries are looked up on our own server using
IP geolocation by DB-IP. We do this
because we have a legitimate interest in knowing how the site is used.
Automate launch list. If you ask to be told when Automate opens, we keep your email address, your name if you give it, and where your visit came from (for example a search engine or an advert), only to send that one email. We delete the list once it has gone out, and we will remove you sooner if you ask.
Server logs. Like all web servers, ours keeps standard access logs, which include IP addresses, for a short time for security and fault-finding.
Your rights. You can ask what we hold about you, and ask us to correct or delete it. If you are unhappy with how we handle your information, you can complain to the Information Commissioner’s Office at ico.org.uk.
