A certification authority is needed to generate and create digital certifications for both public and private use. Oftentimes the issuing party is a third party contracted by a business to create their certificates. This third party has to be a trusted source in order for people to have confidence that security will not be compromised. This confidence applies to both internal and external usage of your certificates.
You Have Options When Selecting a Certification Authority
There are different options available for selecting and using a certification authority. The options you select will often depend on the size of your business as well as the level of responsibility you want to have over creating your own digital certificates. You can choose between traditional CA systems, which include using a managed service, or obtaining your own CA software. Another solution, which offers more flexibility, is using a shared CA solution.
