Sign your emails as the verified professional you are

Individual Validation S/MIME (IV S/MIME) puts your verified first and last name into every digital signature — so clients, patients, and counterparties know exactly who sent the email and can trust it hasn’t been tampered with. Ideal for lawyers, doctors, accountants, engineers, notaries, and any professional whose personal identity is central to their communications.

 

Professional identity — verified and signed into every email

IV S/MIME builds on the signing and encryption capabilities of Basic S/MIME by adding a validated layer of personal identity. SSL.com verifies your first and last name against official documentation before issuing the certificate — and your verified name appears in the digital signature attached to every email you send.

For professionals whose clients or patients place significant trust in their personal identity — lawyers signing engagement letters, doctors communicating with patients, accountants sending financial documents — IV S/MIME transforms your email signature from a self-assertion into a verified credential.

Why professionals use IV S/MIME

Verified identity in every signature

Your first and last name, validated by SSL.com, appears in the digital signature — not just the “From” field

End-to-end encryption

Email content encrypted before leaving your device — only the intended recipient can decrypt and read it

Tamper-evident signing

Any modification to the email after sending breaks the cryptographic signature — immediately detectable by recipients

Professional credibility

Clients and counterparties see a CA-verified identity, not just a name you typed — builds trust in high-stakes communications

Ideal for regulated professions

Lawyers, accountants, engineers, doctors, notaries — professions where personal identity in written communications carries legal and professional weight

IV S/MIME is the right choice for…

  • Lawyers signing client engagement letters, contracts, and correspondence
  • Accountants and auditors sending financial reports and tax documents
  • Engineers signing technical specifications and project communications
  • Doctors and healthcare professionals communicating with patients and colleagues
  • Notaries signing and authenticating documents via email
  • Any professional whose personal identity in email communications carries weight with clients
Need to represent your organization too? If you need both your personal name and your organization’s name in the digital signature, Sponsor S/MIME (IV + OV) provides both — ideal for professionals who communicate on behalf of a firm, practice, or employer.
