Website Security Checks Businesses Must Do in 2026 to Build Digital Trust


Safer Internet Day highlights the importance of trust online. Learn the website security checks businesses should prioritize in 2026 to protect users and brands.

Internet security is a never-ending pursuit, and Safer Internet Day is a timely reminder that building a safer digital environment requires ongoing attention. The annual day of observance reminds us that the public must feel "empowered to use technology responsibly, respectfully, critically and creatively." In 2026, this movement encourages us to come "Together for a Better Internet."
Although largely focused on students and families, Safer Internet Day reinforces an important responsibility for businesses. As digital threats continue to escalate, organizations are expected to protect the users who rely on their online services.
One-off or status quo security fixes are no longer sufficient; maintaining digital trust now requires proactive, layered defenses across every digital touchpoint. Websites, email, and software experiences must work together to establish encryption, authentication, and validation that users can rely on.
To support organizations strengthening cybersecurity in 2026, Sectigo is offering 10% off digital certificates and security products with code SAFER10 (valid through March 10, 2026).

What does digital trust mean for modern businesses?
Digital trust reflects confidence in the systems and platforms that enable online interactions. It is a baseline expectation that digital services (and the organizations that provide them) will protect users. Consumers use digital trust signals to decide whether a website, email, or application is safe to use and resilient against modern threats.
For businesses, digital trust is a strategic foundation, not a reactive security measure. It shapes security programs across software development, infrastructure, and data governance, helping organizations move beyond one-off fixes toward adaptive, intelligence-led approaches that address risk at its source.
Managing trust across websites, email, and software
Digital trust is not established through a single control or technology. For businesses, it is shaped by how consistently security and identity protections are applied across every digital interaction users have with the organization.
For most organizations, digital trust is built through three interconnected areas:
- Website trust. Promoting a secure online presence and safe browsing, website trust inspires confidence in users, who expect to navigate legitimate websites and who want to be reassured that their sensitive information will be protected.
- Email trust. Treating email as an extension of an organization's web presence, email trust involves proactive measures meant to combat issues such as phishing and spoofing, which can erode user confidence and undermine credibility.
- Software and application trust. Focused on downloads and APIs, software and application trust centers around the tools and apps that today's businesses build or utilize. Unsigned and outdated code can introduce new risks, ultimately jeopardizing trust across the entire digital ecosystem.
Website security checks to prioritize in 2026
Security checks support digital trust by verifying that systems continue to remain effective over time. Prioritizing these checks means acknowledging that trust is not assumed, but rather, actively built and maintained through consistent monitoring and validation.
For organizations, the following security checks help maintain digital trust:
1. Check SSL/TLS certificates are valid
Organizations should routinely verify that all SSL/TLS certificates in use are valid, properly configured, and actively protecting user connections. These certificates remain a foundational component of digital trust, providing both authentication and encryption while signaling to users and browsers that connections are legitimate.
Because digital certificates expire and lifespans continue to shorten, discovery and ongoing management are critical. This begins with establishing a detailed inventory, while also tracking expiration dates and verifying that certificates are properly configured.
2. Prepare for certificate lifecycle management at scale
Amid quickly growing certificate volumes and frequent renewals, there is a greater need for automated solutions that help organizations manage certificates at scale. This is a great time to move away from manual workflows and prepare for the quickly approaching shift to 47-day certificate lifespans. The first big shift in validity periods is right around the corner: 200-day lifespans will take effect in March, 2026.
To prepare for this shift and reduce operational risk, businesses should build automation into the entire certificate lifecycle management process, including discovery, issuance, renewal, and revocation. Scalable, automated certificate lifecycle management (CLM) positions enterprises to avoid outages and maintain trust as certificate volumes grow and as turnover accelerates.
3. Continuously scan for vulnerabilities and malware
Every year brings new attack vectors, leaving previously effective cybersecurity strategies vulnerable to gaps that sophisticated threat actors can exploit. At this point, one-off security scans fall short; these must be replaced by continuous security scans, ensuring that weaknesses are detected as soon as they emerge and long before they can be weaponized.
Solutions such as SiteLock use daily security scanning to detect malware and known vulnerabilities before they can be exploited. This helps organizations identify and remediate several cybersecurity risks, including those identified in the OWASP Top 10.
4. Review permissions and authentication controls
Organizations should regularly review permissions, access rights, and authentication methods to identify weak controls or outdated credentials that could enable unauthorized access or brute force attempts. This review should confirm that only the appropriate users, systems, and services retain access to sensitive functions and data.
It is increasingly evident that passwords alone are no longer sufficient for reliable access control. As part of this review, businesses should evaluate whether password-centric approaches, including traditional multi-factor authentication, are appropriate for critical systems or whether certificate-based alternatives should be implemented. Certificate-based authentication uses private keys as cryptographic proof of identity and aligns with modern least-privilege and zero-trust models, in which trust is never assumed, but rather, actively verified.
5. Strengthen email trust
Email trust should be reviewed alongside website trust, as both depend on domain ownership and identity verification. Organizations should first confirm that email authentication protocols such as SPF (Sender Policy Framework), DMARC (Domain‑Based Message Authentication, Reporting, and Conformance), and DKIM (DomainKeys Identified Mail) are correctly configured and actively enforced for their sending domains.
Once these controls are in place, businesses can further strengthen email trust by using Verified Mark Certificates (VMCs), which display logos directly within recipients' email inboxes. Common Mark Certificates (CMCs) offer a viable alternative when registered trademarks are not yet available. Mark certificates can lead to improved brand recognition and open rates, but also prevent phishing by making it difficult for attackers to impersonate brands.
6. Secure software and code
Organizations should review how software, scripts, and applications are developed, tested, and delivered to users. This includes confirming that secure coding practices are in place and that security testing is integrated into the DevOps lifecycle to identify issues such as cross-site scripting and other common vulnerabilities early in development.
As part of this review, businesses should verify that code signing is used for software, scripts, and updates distributed to users. Code signing certificates verify software origins and integrity prior to deployment. By protecting against unauthorized modification, code signing certificates reduce operational friction and preserve integrity across the software lifecycle.
7. Monitor trust signals that impact users and browsers
Trust signals provide businesses with visible indicators that users and platforms rely on to assess legitimacy and safety. These signals include security badges, HTTPS indicators, or Verified Mark Certificates (VMCs) displayed within email inboxes. Because these indicators influence user confidence, they should be treated as active checks rather than "set and forget" strategies and monitored alongside other security controls.
Mechanisms such as safe browsing warnings and blacklists act as early-warning systems when a site is suspected of malicious behavior. While these protections improve user safety, they also surface trust failures directly to users, often through warning screens or blocked access. Monitoring trust signals and maintaining strong security hygiene helps organizations identify issues early and reduce the risk of browser warnings, blacklist entries, traffic loss, or reduced search visibility.
8. Assess readiness for post-quantum cryptography
The quantum era is rapidly approaching. Organizations should assess where and how cryptography is used across websites, applications, email systems, and internal infrastructure to evaluate their current level of crypto agility. Post-quantum cryptography (PQC) is no longer a distant consideration and should be incorporated into long-term security planning.
Already, attackers may be collecting sensitive data, using harvest now, decrypt later schemes to wait out advances in quantum computing. Organizations can combat these threats by determining where data may be at risk and by identifying classical algorithms that may require replacement with quantum-safe alternatives. Quantum-safe and hybrid certificates can enable a smoother transition.
