It depends on your requirements. Anyone can install a free SSL certificate, as they are accepted by all well-known web browsers, such as Google Chrome. However, the free SSL certificate should not be considered as a complete trust solution, as it comes with certain disadvantages, including:
Low Trust Factor: Free SSL certificates provide only basic security indicators, which may not inspire the highest level of trust.
Limited to DV (Domain Validation): Free SSL certificates are typically available only in the Domain Validation (DV) type. This limitation makes them less suitable for securing e-commerce or corporate websites that require higher levels of validation.
Short Lifespan: Free SSL certificates often have a relatively short validity period, typically lasting only one to two months. This frequent renewal can be inconvenient.
Commonly Used for Testing: Free SSL certificates are commonly used for testing and development purposes rather than for production websites.
