The threat landscape for email security is a pressing concern for organizations worldwide. Phishing has been the single most devastating cybersecurity threat since email became public in the late 1980s to early 1990s, and it still works 60% of the time.

Email is the primary method for delivering malware, and a compromised email account can have more value than other sources. The World Economic Forum ranks cybercrime eighth among the world's top 10 global risks, just after climate change.

Humans are at the center of all cyber threats, with 68% of breaches involving a human component. The median time users fall victim to phishing emails is less than 60 seconds, and nearly 30% of malicious emails detected in 2024 involve social engineering.

Business email compromise (BEC) is one of the enterprise organizations' most significant cybersecurity threats, with $2.9 billion lost in 2023 alone. Email is both a means of attack and a high-value target for company intelligence and financial fraud.

Despite efforts to combat cyber threats, phishing, business email compromise, and account takeovers are still happening and on the rise. A staggering 83% of organizations have experienced email data breaches, which presents serious risks to the security of client and company data.

Human error is the primary cause of the rise in data breach incidents, with employees unintentionally sharing sensitive information with the wrong people or attaching the wrong files in 24% of email data breaches.

A fresh viewpoint: Microsoft Security Phishing Email

API-based solutions have revolutionized the way we approach email security. By integrating directly with email platforms, these solutions can provide more effective security measures than traditional MX record-based approaches.

For instance, Microsoft 365's Microsoft Graph API allows third-party service providers to query and manage delivered emails, making it possible to implement email security within the corporate email platform. This can be set up quickly and easily via OAuth authentication.

API-based solutions can offer a range of services, including anti-spam, anti-malware, anti-phishing, and URL filtering. Some examples of these services include:

In fact, Check Point Harmony Email is 44x more effective at keeping phishing emails from reaching a user's inbox than legacy email gateways using MX record approaches.

Mimecast M2 is a traditional gateway approach to email security, but it has some significant shortcomings. It forces customers to modify their MX records, which is a complex and invasive process.

This approach publicizes the email security solution an organization uses, allowing attackers to customize their attacks. Modifying MX records only reroutes incoming email from outside the domain, leaving an organization exposed to internal threats, which make up 35% of attacks.

Mimecast M2 relies on basic anomaly detection, which analyzes email contents with no dynamic analysis. This means it can't catch advanced evasion techniques.

Mimecast M2's sandbox is incapable of catching advanced evasion techniques, and it only uses static dictionary matching to identify impersonation in phishing emails. This provides less protection than real-time analysis.

Mimecast M2 requires disabling built-in security features in Microsoft 365, reducing overall security. Administrators must manually define data types for Data Loss Prevention (DLP), which is complex, time-consuming, and runs the risk that an oversight will result in the leakage of sensitive information.

Here are some of the shortcomings of Mimecast M2:

APIs offer a more effective way to provide email security compared to MX record-based approaches. This is because APIs allow for direct integration with email solutions, eliminating the need to reroute emails.

Using APIs like Microsoft Graph, a third-party provider can query and manage a user's delivered email. This is done via OAuth authentication, which is a quick and easy setup process.

API-based email security solutions can offer various services, including anti-spam, anti-malware, anti-phishing, and URL filtering. These services can be more effective than legacy email gateways using MX record approaches.

For example, Check Point Harmony Email is 44x more effective at keeping phishing emails from reaching a user's inbox than legacy email gateways.

Some examples of services that can be offered through API-based integration include:

Lack of OS integration is a significant challenge in the email encryption market. This is because portal-based encryption solutions require users to go through login procedures every time they want to access an encrypted email.

Users find this inconvenient and may look for less secure options. Excessive inconvenience can lead to a decline in adoption and utilization of email encryption.

Encryption services like S/MIME and PGP are safe, but they may not integrate well with different operating systems. This makes it difficult to send and receive encrypted messages.

User interfaces are frequently neglected when developing encryption tools, which irritates users. Extra procedures needed for encrypted emails, like exchanging keys or using secure email clients, can be time-consuming and inconvenient.
