Yes, you are still protected with a free SSL certificate, but the level of protection and the features offered might differ from a premium SSL certificate. Here's a breakdown of how a free SSL certificate generally protects you:
-
Encryption: The primary function of any SSL (Secure Sockets Layer) certificate, free or paid, is to encrypt data transmitted between the user's browser and the website server. This means that any information exchanged, like personal details, login credentials, or payment information, is protected from eavesdropping or interception.
-
Basic Validation: Free SSL certificates typically offer Domain Validation (DV). This means the certificate authority verifies that the applicant has control over the domain. DV does not include organizational validation, but it's sufficient for encrypting data.
-
Trust Indicators: With a free SSL, browsers will display a padlock symbol in the address bar, indicating that the connection is secure. This helps in building trust with visitors, as they can see that their data is encrypted.
However, free SSL certificates often lack certain features and assurances that come with premium SSL certificates:
-
Warranty: Premium SSL certificates often come with a warranty that can protect you against certain losses in case of SSL failure (rare, but can be a consideration for businesses).
-
Extended Validation (EV): Premium SSL certificates can offer EV, where the certificate authority conducts a thorough validation of the business. This includes verifying the legal, physical, and operational existence of the entity. Browsers used to display the organisation's name in the address bar for EV SSL, but this is less common now.
-
Customer Support: Paid SSL providers typically offer better customer support, which can be crucial for businesses in case of issues.
-
Additional Features: Some premium SSL certificates may come with additional security features like malware scanning, more extensive warranties, or higher levels of encryption.
In summary, a free SSL certificate provides basic security and is suitable for personal websites, blogs, or small businesses that don't handle sensitive transactions. For larger businesses, e-commerce sites, or when handling sensitive data, investing in a premium SSL certificate can offer greater assurance and additional features.
