Regulatory enforcement and rising consumer awareness drive businesses to prioritize secure communication solutions to ensure compliance and trust.

Rising Implementation of Zero Trust Architecture

Zero Trust Architecture is becoming increasingly popular as companies shift away from conventional perimeter-focused security approaches. In email encryption, zero trust requires strict identity verification for every access attempt whether inside or outside the corporate network. Emails are protected through continuous authentication, encryption, and monitoring ensuring that only authorized recipients can access sensitive content. For instance, in December 2024, Cognizant announced its partnership with Zscaler to deliver AI-powered zero-trust security solutions aimed at streamlining security processes for businesses. This collaboration addresses rising operational costs and evolving cyber threats promising enhanced protection and improved user experiences for organizations navigating a complex digital landscape. This approach minimizes the risk of data breaches by assuming no user or device is inherently trustworthy. It is particularly critical in remote work environments and hybrid cloud systems where data flows across distributed networks.

Growing Cloud-Adoption

The widespread adoption of cloud-based encryption is a direct response to the widespread shift of businesses to cloud email platforms like Microsoft 365 and Google Workspace. These platforms store vast amounts of sensitive data, making them prime cyberattack targets. To address this, organizations are integrating robust encryption solutions to protect data in transit and at rest. Cloud-based encryption offers scalability, flexibility, and real-time protection, ensuring data security without disrupting workflows. It also supports compliance with regulations like GDPR and HIPAA, which require stringent data protection measures. As businesses prioritize digital transformation, demand for secure cloud-based email solutions continues to surge. For instance, in April 2024, KnowBe4 announced its plans to acquire Egress a leader in cloud email security. This acquisition enhances KnowBe4’s AI-driven cybersecurity offerings providing organizations with tailored security solutions and training to combat human-related data breaches ultimately fostering a stronger security culture amid evolving cyber threats.
