Discover how Common Mark Certificates enable you to display your brand logo in email inboxes. No trademark required. Boost trust with CMCs and BIMI.

Shrinking certificate lifespans are exposing long-hidden security debt in digital trust infrastructure. As certificates move toward 47-day validity, manual processes, poor visibility, and legacy systems increasingly lead to outages and business disruption. Organizations must treat certificates and keys as first-class infrastructure, automating inventory, renewal, and governance to reduce risk, maintain uptime, and restore trust at scale.

A Cryptography Bill of Materials (CBOM) gives enterprises a structured, contextual inventory of cryptographic assets such as keys, algorithms, and digital certificates. More than a simple list, a CBOM improves visibility, governance, and risk management by showing how cryptography supports business operations and where vulnerabilities exist. As quantum computing, algorithm deprecation, and compliance pressures increase, CBOMs help organizations build crypto agility, accelerate incident response, and prepare for post-quantum security when paired with automation.

BIMI (Brand Indicators for Message Identification) is an email authentication standard that strengthens inbox security while enhancing brand visibility. By displaying verified brand logos in supported inboxes, BIMI helps users quickly identify legitimate emails and avoid phishing attempts. Built on foundational protocols like SPF, DKIM, and DMARC, BIMI requires strict authentication enforcement and logo validation through Verified Mark Certificates (VMCs) or Common Mark Certificates (CMCs). The result is improved trust, reduced impersonation risk, and stronger engagement for organizations that rely on email as a core communication and marketing channel.

State and local government institutions face escalating cyber risks in 2026 due to limited budgets, understaffed IT teams, expanding digital footprints, and aging infrastructure. As attack surfaces grow and SSL/TLS certificate lifespans shrink toward 47 days, manual security processes become unsustainable. Strengthening cybersecurity requires a strategic shift toward Zero Trust, automation, and especially automated certificate lifecycle management (CLM). By improving visibility, ensuring timely certificate renewals, securing hybrid environments, and supporting crypto agility, automation enables governments to protect sensitive data, maintain essential services, and build long-term cyber resilience.

Transport and logistics organizations face rising cyber threats, complex global infrastructures, and growing reliance on SSL/TLS certificates to secure critical operations. As certificate lifespans shrink to just 47 days by 2029, manual certificate management becomes unsustainable, increasing the risk of outages, supply chain disruptions, and security breaches. Automated Certificate Lifecycle Management (CLM) helps T&L organizations maintain uptime, reduce human error, strengthen zero-trust security, and stay resilient in the face of escalating threats and regulatory pressure.

A digital signature is a PKI-based digital certificate that authenticates the identity of the signer and ensures electronically transmitted documents and digital messages have not been forged or tampered with. Digital signatures are similar to physical signatures in the sense that both are unique to the signer, except that in the case of digitally signed documents, a digital signature offers far more security and the assurance of the document’s origin, identity, and integrity. Based on the highest standard of security, digital signatures are legally binding in the United States and many other countries.

Harvest now, decrypt later (HNDL) attacks are a rising cybersecurity concern, with quantum computing set to break traditional encryption methods. Organizations must act now to build crypto agility and adopt quantum-resistant strategies. Learn how Sectigo supports proactive preparation against future quantum threats.

Public sector agencies depend on digital certificates to secure communication, authenticate identities, and protect critical infrastructure. However, growing certificate volumes, short lifespans, complex environments, and increasing cyber threats make manual certificate lifecycle management (CLM) unsustainable. Automated and centralized CLM improves visibility, reduces outages, strengthens compliance with FISMA and other regulations, and ensures secure, resilient public services.

Learn about the different types of SSL certificates: Extended Validated (EV), Organization Validated (OV) and Domain Validated (DV). Each type offers a unique level of security, verification depth, and purpose. Learn how they work, how they differ, and which option is best for your website.
