Why choose a Sectigo SSL vs a free one like Let's Encrypt?
| Aspect | Free certificates (Let's encrypt) | Sectigo |
|---|---|---|
| Certificate types | Only offers DV (Domain Validation). There is no OV or EV, which limits identity validation and visual trust (e.g.: green bar or company details). | Offers DV, OV and EV, more options depending on the required level of validation and trust. |
| Technical support | No dedicated support. Only community and documentation. | Has official technical support SLA, chat, email and enterprise assistance. |
| Warranty | Does not offer an economic guarantee in case of certificate problems. | Includes financial warranty (depending on certificate, up to $1.75M USD). |
| Certificate duration | Maximum 90 days, requiring automated renewal (risk if the process fails). | Can issue certificates for 1 year (and more in the past), reducing management frequency. |
| Advanced compatibility | No code signing, S/MIME or multi-domain OV/EV certificates. | Offers special certificates: code signing, S/MIME, wildcard and EV, multi-domain OV/EV. |
| Support in corporate environments | Can be seen as "less formal" since it's free and has no guarantee. | Commercially recognized, more accepted in compliance audits and large corporations. |
| End customer trust | Since it's only DV, it doesn't prove the domain owner's identity, which can generate lower perceived trust in commercial services. | OV and EV validate companies and increase user credibility and trust. |

Why SSL?
Why secure a site with SSL?
Data encryption:
With the use of the https protocol, all information exchanged between the visitor's device and the server travels encrypted. This way, if intercepted, it would be completely illegible to the attacker.
Website authentication:
SSL Certificates are also responsible for verifying the authenticity of the website. Visitors can access the certificate information to make sure they have entered the genuine website and not a fake version created to steal their data.
The browser (or client) requests the server to identify itself.
The server sends a copy of its SSL Certificate to the browser (or client).
The browser (or client) verifies the validity of the SSL Certificate and, if it trusts it, sends a message to the server.
The server returns a digitally signed message to start a session with data encryption.
On sites where personal data is requested.
In hosting Facebook applications.
In corporate intranets.
In backend or admin panels.
On E-commerce sites.
Access requiring username and password.
Where online transactions are carried out.
Where online payments are made.
Email services.
Mobile device applications.
Visitors' sensitive information travels encrypted and safe from malicious hackers.
Without SSL, browsers display a message indicating that your site is "NOT SECURE"
In search results, sites with SSL are prioritized over those without it.

Excellent experience as a DonWeb user. Fast responses; very good willingness to attend to inquiries; and expertise to resolve technical issues (which have not been many in my case, and none of them attributable to the service provider, but to my own lack of knowledge).

I had a dispute over a domain that was infringing trademark law. I reported it to DonWeb, which was the site where it was purchased, and once they received all the documentation supporting my complaint, they acted with impressive speed. Federico S is a genius.

Yes, you can purchase the SSL Certificate at DonWeb even if your site is hosted with another provider. In that case, it's important that you first check with your hosting provider whether they allow installing SSL certificates issued outside their platform. If they do, you can download the certificate credentials from DonWeb and install them on the server where your site is hosted. Keep in mind that the installation and any associated cost will be the responsibility of your current provider.
If your site is hosted on a DonWeb web hosting service (including Cloud Server or Dedicated) you don't need one. If you host your site externally, contact your hosting provider to find out the assigned IP.
The SSL Sectigo Positive Certificate protects a single domain, both with and without www (for example: yourdomain.com and www.yourdomain.com).
If you want to protect a different domain, you need to purchase an additional certificate. If you want to secure all subdomains of the same domain (for example: system.yourdomain.com, blog.yourdomain.com, etc.), the appropriate option is the SSL Sectigo Positive Wildcard Certificate.
No. SSL certificates only protect the content of a website accessed through the "https" protocol
Yes. All content under the domain for which the SSL certificate was purchased, including internal folders. For example: https://hosting.com/hola.png and https://hosting.com/archivos/index.html.
Since 2014 Google has considered HTTPS usage a ranking factor, and since 2024 its weight has been key. Having an SSL certificate not only protects users' data, but also improves visibility, ranking, and trust in your website.
No. When you purchase an SSL certificate like Thawte 123 or Rapid SSL, you must purchase it for www.yourdomain.com and yourdomain.com will also be included in the protection.
Yes. All certificates offered by DonWeb are optimal and meet all the requirements that different social networks impose on app developers.
You can, but it's not necessary. Actually, you can host all your apps under the same domain in different folders.
Example: https://myapp.com/app1, https://myapp.com/app-promotions, https://myapp.com/app10, etc.
Another option is to purchase a Wildcard type certificate and host each application on a different subdomain.
E.g.: https://app1.myapp.com, https://app-promotions.myapp.com, https://app10.myapp.com, etc.
Yes, it's possible to change it (except in OV certificates). Keep in mind that, when making this change, the certificate must be reissued from scratch, so it will be necessary to repeat the entire validation process.
The SSL supports unlimited subdomains.
Yes, it's possible to change it (except in OV certificates). Keep in mind that, when making this change, the certificate must be reissued from scratch, so it will be necessary to repeat the entire validation process.
The free certificate installation is performed for services with Ferozo Hosting Panel (web hosting plans, SitioSimple, Dedicated servers and Cloud).
Installation is not included for:
Services with CPanel (cloud and dedicated). CPanel has a tool in its WHM where you can install it.
Services without a Control Panel (cloud and dedicated).
Installation of external certificates has an additional cost.
Depending on how you use your SSL Certificate, you may need the browser to always use the connection via https.
In some cases this doesn't happen automatically; forcing the browser to do so requires making certain changes to your website's programming. Since, for your security, DonWeb doesn't intervene in your site's programming code, you'll need to do it yourself.
