DigiCert SSL and Digital Certificates

A wildcard can suit eligible first level subdomains under one base domain. FLEX becomes relevant when you also need other standard domains or additional wildcard domain families. Review private key sharing before consolidating.

A Multi Domain/SAN or applicable FLEX certificate can cover multiple eligible named domains after validation. A conventional wildcard for one base domain does not cover the other base domain.

They are service/product tiers. Compare support, management, scanning/monitoring, warranty and other current features. Do not assume the higher tier uses inherently stronger TLS encryption.

FLEX allows eligible standard and wildcard names to be mixed under one certificate architecture and expanded within current limits. It is useful when the hostname estate changes frequently.

Not automatically. EV should be selected when policy, procurement, contractual or assurance requirements call for EV. Industry alone does not make EV mandatory.

No universal green bar claim should be made for modern browsers. EV remains a higher assurance identity validation category.

Not from a wildcard pattern of *.company.com alone. That pattern is intended for eligible first level names such as api.company.com.

Not necessarily. Maximum capacity is not the same as recommended architecture. Consider key ownership, application isolation, business unit boundaries and revocation blast radius.

Browsers and clients may show trust errors and integrations can fail. Maintain inventory, ownership, alerts, timely renewal/reissue and automation where appropriate.

No. TLS protects data in transit and authenticates the certificate endpoint. Application security, WAF, patching, MFA, secure coding and monitoring remain separate.

For the software package itself, evaluate Code Signing. Website TLS and Code Signing solve different problems and many software companies use both.

No guarantee should be made. Current platform reputation behaviour is separate from certificate validation, and Microsoft changed SmartScreen behaviour for EV Code Signing.

S/MIME supports signed email and, in compatible workflows, message encryption. It is relevant where sender authenticity and confidential email exchange are required.

They are BIMI related mark certificates for authenticated brand logo display in participating email ecosystems. They are not website SSL certificates.

Yes. The decision should be based on your exact domain list, subdomain pattern, validation requirement, server/cloud architecture, private key boundaries and expected growth.

Use a single site certificate for a stable hostname. Consider Wildcard when several eligible first level subdomains share one base domain and the private key architecture is acceptable.

Many products allow deployment or reissue according to current licensing rules. Confirm the exact product terms and protect the private key during any migration.

The certificate authority verifies domain control and organisation identity using its current validation procedures. Exact evidence can vary by product and organisation type.

Domain validation can often complete quickly when domain control is available. Organisation and extended validation depend on successful identity checks, so issuance time should be treated as conditional rather than guaranteed.

Often yes when the architecture and licence permit it. Confirm where TLS terminates, how the key is stored and whether the same trust boundary should span all endpoints.

Treat the certificate as compromised, revoke or replace it as appropriate, generate a new protected key and investigate how the exposure occurred.

No. A site seal is a visible trust element offered with some products. The underlying certificate validation and TLS connection are separate.

It can be highly automated on supported platforms and products, but monitoring, ownership and failure handling are still necessary.

Assign accountable owners by application or platform, maintain a central inventory, define key handling rules, monitor expiry and document reissue and revocation procedures.

Public certificate support for IP addresses depends on current certificate authority policy and product capability. Verify the exact requirement before purchase.

Only after assessing the trust boundary. Broad key reuse can simplify deployment but increases exposure if one server is compromised.

Confirm the exact hostnames, validation category, wildcard pattern, SAN count, server platform, key ownership, lifecycle process and current commercial specifications.

Support varies by seller and product. NTSPL can provide selection and deployment assistance, while the certificate itself should not be confused with a managed security service.

Some products support changes through reissue or flexible domain configuration within current rules. Verify the selected product before planning frequent hostname changes.

Use a central inventory, responsible owner, multiple expiry alerts, tested renewal procedures and automation where appropriate. Do not rely on a single email reminder.
