Comodo SSL Store InstantSSL Premium [...], $ 102.97/yr.

InstantSSL Premium Wildcard is an organization validated wildcard SSL certificate that secures unlimited subdomains on a single base domain such as *.example.com, making it ideal for businesses running many services under one brand.
With one order you can protect hosts like www.example.com, mail.example.com, login.example.com and other subdomains without having to manage a separate certificate for each.
The certificate uses strong 256 bit encryption with a 2048 bit root and is issued after domain and company details have been validated, including a telephone verification step, with typical issuance completed within one to three business days when documentation is ready.
Browser compatibility extends to around 99.9 percent of current web and mobile clients so visitors to any secured subdomain receive a trusted HTTPS experience.
Premium Wildcard includes unlimited free server licenses, letting you deploy the same certificate across reverse proxies, web clusters, mail gateways and application servers without incurring extra licensing fees.
Unlimited free re issuance enables you to rotate keys, reorganize subdomains or move services between platforms while keeping the wildcard order active for its full term.
A Comodo trust mark associated with the wildcard plan can be placed on landing pages and login screens to emphasise that the underlying organization has been validated and that all subdomains under the protected hostname are covered by a business grade certificate.
The plan offers a relying party warranty of two hundred fifty thousand dollars, reflecting its role in protecting complex sites where many secure endpoints and transactions are concentrated on a single base domain.
Multi year bundles cover one to five year terms, and the effective price per year drops from roughly one hundred thirty eight dollars and ninety nine cents on a single year order to about one hundred two dollars and ninety seven cents on a five year bundle.
Industry rules require the wildcard to be reissued at least annually even on multi year purchases, but there is no additional charge for reissue and reminder emails are sent so validation and installation can be scheduled ahead of time.
This option is particularly attractive where development and operations teams regularly add or change subdomains because the wildcard automatically extends protection to new hosts that match the pattern without requiring new certificate orders.

All certificates in the InstantSSL family share a common approach that combines strong identity checks with practical deployment features designed for business use.
Each certificate is issued as an organization validated product with domain control and company details verified through trusted databases or professional documentation, and contact is made by phone to ensure that the applicant genuinely represents the business.
The certificates use modern 2048 bit roots and support 256 bit encryption, are compatible with almost all current browsers and devices, and include a trust mark that can be embedded on a site to provide visitors with real time confirmation of the organization behind the domain.
Customers can order multi year bundles that reduce the effective yearly price while staying aligned with industry rules by reissuing the certificate once a year, a process that is guided by reminder emails and does not incur additional costs.
Unlimited server licensing and unlimited re issuance mean a single order can be deployed across front end servers, proxies and appliances without having to track per node charges, which is useful for high availability and cloud architectures.
Support is handled by a specialist team that is available around the clock through phone, email, live chat and ticket requests, helping with everything from CSR generation to installation troubleshooting.
All purchases are backed by a thirty day money back guarantee on the original order so organizations can test installation and browser compatibility with confidence, and as a United States based provider there is no separate European value added tax charged on top of the listed prices.
