Email Security and Zero Trust

A Comprehensive Guide


In the ever-changing landscape of cybersecurity, two topics have risen to the forefront of concern: the state of email security and the Zero Trust security model. This expanded article delves deeper into the key takeaways from Mimecast's 2023 State of Email Security report and the increasingly critical need for a Zero Trust strategy.

The State of Email Security in 2023


Mimecast's seventh annual State of Email Security report serves as a wake-up call for organizations worldwide. The report reveals alarming statistics:

  • 59% of respondents say cyberattacks are growing increasingly sophisticated.

  • 75% of companies have experienced an increase in email-based threats.

  • 72% of companies expect to be harmed in 2023 by a collaboration-tool-based attack.

Expanded Key Takeaways

Cyber Risk in the Boardroom: Cybersecurity is no longer an IT issue but a strategic concern that affects the entire organization. Companies must integrate cybersecurity into their business strategies to mitigate risks effectively.

Sophistication of Attacks: The complexity of cyberattacks is increasing, making it essential for organizations to adopt advanced security measures such as AI-driven threat detection and response systems.

Collaboration Tool Risks: As remote work becomes more prevalent, the risks associated with collaboration tools are rising. Organizations must secure these platforms to protect sensitive data and communications.

Human Factor: Employees are often the weakest link in cybersecurity. Training programs focused on recognizing phishing attempts and other email-based threats are crucial.

Regulatory Compliance: With the introduction of stricter data protection laws, organizations must ensure they are compliant to avoid hefty fines and reputational damage.

The Increasing Need for a Zero Trust Strategy

Why Zero Trust?

The traditional 'trust but verify' model is no longer sufficient in today's complex digital landscape. The Zero Trust model, which operates on a 'never trust, always verify' principle, is increasingly becoming a necessity.

Key Points on Implementing Zero Trust

Microsegmentation: This is not just a technical requirement but a strategic move. By breaking the network into smaller segments, organizations can better monitor and control data flow, making it easier to identify and contain threats.

Least Privilege Access: Implementing this principle is about more than just limiting access. It's about understanding the roles and responsibilities within your organization and tailoring access accordingly.

Multi-factor Authentication (MFA): MFA should be a standard practice, not an optional feature. It adds an extra layer of security that can deter most attackers.

Real-time Monitoring and Analytics: These tools provide more than just alerts; they offer insights into user behavior and network performance, helping organizations preemptively identify potential vulnerabilities.

Cultural Shift: Adopting Zero Trust is not just a technological change but a cultural one. It requires buy-in from all levels of the organization.


The evolving nature of cyber threats makes it imperative for organizations to continually update their security measures. The state of email security is a growing concern, and the adoption of a Zero Trust strategy is increasingly becoming a necessity rather than an option. Organizations that proactively address these issues are better positioned to safeguard their assets in this digital age.
