Maintaining adequate levels of security across multiple domains can be very challenging, although it is essential if you want to avoid costly breaches and maintain the trust of customers and clients.

One solution to consider is grouping all your domains with a UCC/SAN, and there are several positive points provided by multi-domain SSL certificates compared with the alternatives.

So that you can appreciate some of the finer points of this issue, here is a look at the aspects that might motivate you to embrace multi-domain SSLs.

Comprehensive coverage

To get started, it is worth pointing out that those organizations which stand to gain the most from multi-domain SSL certificates are those that either has presences across a number of different global regions, or those which act as an umbrella within which lots of other businesses and brands need to be managed.

In both of these cases, it is highly likely that you will be responsible for a wide variety of domains and subdomains, each of which of course needs to be suitably well protected from the threats facing it. This is where SSLs that encompass multiple domains rather than a single instance will be most effective, for obvious reasons.

You can use a UCC/SAN to cover tens or even hundreds of domains at once, which is a major convenience as well as being advantageous from a cost perspective.

For example, say you have a website with a .com address that is specifically targeted at customers in North America, while also operating a site with the domain name but using .au TLD to cater to visitors from Australia. With a multi-domain SSL, you could cover both of these sites and many more besides with just one certificate as opposed to several.

This comprehensive coverage of course extends beyond website domains and can also include everything from Microsoft Exchange servers to services which you use to manage the multitude of mobile devices that are issued to employees within your organization.

Impressive flexibility

Another perk that comes with this type of SSL certificate is that it affords you the ability to make changes without having to completely overhaul your security setup.

At some point, you might want to add a new domain when you launch a website for your business in a new country or region of the world that you have yet to penetrate, or when you open a new business or launch a new brand in a particular market niche. In this case, you can use your multi-domain SSL certificate to provide instant protection for this fledgeling platform, without having to go through the rigmarole of procuring an entirely unique stand-alone certificate.

Likewise, when the need to remove a domain arises, for whatever reason, you can easily edit and adjust your multi-domain SSL certificate to reflect this. In short, you will be in the driving seat at all times and the certificate will be flexible enough to encompass a huge range of requirements and scenarios stretching off into the future.

Undeniable affordability

The cost-saving benefits of multi-domain SSL certificates have already been touched upon, but it is worth expanding on why this is relevant, particularly in the case of larger organizations, companies, and corporations.

Using a single certificate to cover a cavalcade of domains makes far more sense from a financial perspective than relying on different certificates purchased again and again for individual domains that fall within your remit.

The cost-effectiveness is not just present in the short term from a procurement perspective, but also in the long term since you will not need to invest time, money, and resources into managing multiple SSLs.

Security & compatibility

These two factors are worth considering in tandem since they are integral to ensuring that your customer-facing sites and services are able to gain traction when they are launched, attract new users if they are established and sustain the reputation of your brands over the years.

Modern multi-domain SSL certificates provide 256-bit encryption to ensure that data is not exposed and thus the attempts to infringe on the security of your site by cybercriminals will be much less likely to succeed.

In turn, this will mean that visitors can put their trust in your domains, which will bolster the reputation of your company and help to stimulate growth.

Finally, there is the widespread compatibility and trust that is placed in multi-domain SSL certificates by the vast majority of the most popular browser solutions in use today. This will let visitors across every conceivable device, OS, and browser combination know that your site is secure and that your firm takes threats seriously.

There are different multi-domain SSL certificate packages to consider, of course, so choose carefully and make sure the setup you select fits the scope of your requirements.
