Multi-layer Email Security for the Mid-to-Large Enterprise Market

The global COVID-19 pandemic has been unprecedented and staggering, with security solutions experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. Based on our analysis, the global market exhibited a rise of 7.7% in 2020 as compared to 2019.

What is Email Security Software?
Email security refers to the prediction, prevention, and detection framework used to provide attack and access protection for email messages. Email security covers mail servers to user behavior, content security, supporting processes, systems, and adjacent security architecture. To be effective, email security requires not only selecting the right products but also having the correct operational procedures in place.

Clients working in highly regulated industries must be concerned about email security, especially with cloud-based emails. Securing email, enforcing stringent policy requirements, and malware protection are top-of-mind for every company, not just the regulated industry.

Enterprise adoption of cloud office systems such as Office 365 and Google Workspace is on a clear upward trajectory, with 70% of companies now using cloud email solutions, according to the Market Guide. Significant shifts to remote work have continued to fuel this adoption.

The growing importance of email security in the enterprise space

Increasing emphasis on greater email protection is one of the prime reasons behind the significance of the email security market. This matters the most as every company intends to safeguard the data within the email. Most importantly, they thrive on protecting the accounts from the threats of viruses and a whole range of software-related issues.

A growing number of social spam

Increasing cases of social spam and phishing emails are also one of the foremost reasons behind the boost of the email security market around the globe. Most importantly, it has become essential for companies to emphasize most of these aspects as one can’t just ignore these things.

Stopping inbound email phishing, spearing phishing, and social engineering

Accuracy in blocking email phish attacks is no longer an accurate measurement of an email security solution. Hackers shift toward reverse social engineering and plaintext attacks to lure internal users. Gartner estimates that 40% of ransomware attacks originate from email. Protection against email threats needs to scale beyond a single security adaptive control.

Approaches to cybersecurity technology

Cyber threats have been relatively constant for companies of all levels. Primarily, attackers aim at stealing crucial data of the clients and customers from the email. This makes the scope of boosting investments in the email security market even higher.

Emphasis on the cloud-based secure email gateway

Gartner clients increasingly express frustration with the operational complexity of the modern security stack. Given the human capital constraints, efficient cybersecurity remains out of reach for most organizations. As such, there is an increased desire to consolidate security products into multifunction solutions addressing a broad set of related challenges, such as securing “hybrid work” or “cloud workloads.” 

The security market will always be fragmented.

What are the critical pillars for email security?
Gartner’s analysts say that. “With the rise of Business Email Compromise-type phishing, no secure email gateway (SEG) is 100% effective in blocking all attacks. This increase requires an additional email security solution for organizations. Ransomware, impersonation, and account takeover attacks are increasing and causing direct financial loss as users place too much trust in the identities associated with email.

The evolution in these types of threats has led to an increased demand for new techniques and services.

Legacy SEG systems are no longer able to keep up with the four pillars of email security:

• Inbound. Advanced threats like BEC and phishing, impersonations, and account takeovers are being missed and labeled as false negatives.
• Outbound. Outbound emails containing sensitive data are being sent unsecured BEC. Because of misconfigurations of DLP/classification. When emails are encrypted, a significant. A percentage is abandoned without being opened because recipients can’t be bothered. The cumbersome processes (usernames, passwords) required to start using encrypted emails.
• Archiving. Storing data for e-discovery and compliance requires vast storage and is very difficult to search and share.
• Account Takeover Detection. Cybercriminals can spend weeks or months inside an organization’s infrastructure, while monitoring, stealing, and changing data without a system Admins were having any knowledge of a breach.

The need for email archiving for compliance and e-discovery
Email archiving is required for organizations that face any form of e-discovery for lawsuits. Several states, including California (CCPA), mandates organizations to retain copies of the email for legal discovery purposes. Organizations will send a retention period on all emails to ensure that only relevant emails are kept within the system.

Enterprise organizations leveraging intelligent indexing for e-discovery

Intelligent Indexing enables rapid data retrieval, even for email servers with years’ worth of high-volume email archives. Access to search data can be granted or revoked at any time, providing a complete audit history of actions conducted on the user’s system. These email archives can serve as a comprehensive historical reference independent of the user’s backup mechanisms. These capabilities give end-user organizations a competitive edge, boosting productivity with quick and straightforward searches while safeguarding data.

Compliance requirements for mid-enterprise market
Clients working in highly regulated industries are especially concerned about email security.

This mid-enterprise market segment requires more adaptive controls that fit into the security operations management structure and cost. Often this segment is audited with a greater frequency than an SMB client.

Many of these organizations are bound to several national and international compliance mandates, including:

GDPR

NIST

CCPA

POPIA

With increased audits and mandates, mid-to-large enterprise space would benefit from a multi-layer solution platform.

Multi-layer email security strategy
Gartner determined by 2023, most clients will deploy some level of multi-layer email protection. Organizations from the SMB, enterprise and global accounts face similar attacks against their users, supply chain partners, and employees.

With the rise of multiple-layer email protection solutions, the cost has increased, scalability has improved, and most of these platforms now offer APIs for integration into Microsoft 365 and Gmail.

Trustifi provides additional email security protection by sitting behind Microsoft 0365 and Google G-suite. Trustifi’s advanced AI and ML capabilities help catch other spam and malware not caught by Microsoft email security.

Why the need for augmentation of email security?
No email solution is 100% proven to stop every email attack. Gartner recently observed how much spam and phish emails still penetrate the end users even with solutions like Microsoft deployed.

The email threat vector changes every day. New attack variances, including whaling phish emails and ransomware malware, impact global organizations daily. Updating the email security layer to combat these attacks is challenging for every vendor.

Traditionally, malicious emails might contain viruses, trojans, harmful attachments, etc. Microsoft is okay for handling these, which currently only constitute about 5 or 10% of the new types of malicious emails landing in your email boxes. Microsoft cannot control the new phishing methods without using an AI engine and advanced text analysis for spam.

Why Trustifi?
Trustifi’s relay-based security uses sophisticated anomaly detection techniques like natural language understanding (NLU) and natural language processing (NLP). It is specifically designed to address BEC by

leveraging AI-powered features that identify these challenging new ongoing conversation phishing attacks, which standard security email gateways can’t detect.

Trustifi’s email security solutions feature a comprehensive suite of email tools for advanced threat protection, easily configurable Data Loss Prevention, and enterprise email security. Trustifi’s easy-to-use software is unmatched in its user-friendliness, flexibility, and cost-effectiveness. Trustifi’s time to value, ease of deployment, and lower cost of ownership for SecOps make the company culture secure and a financial match for any client seeking email security, data exfiltration, and message encryption.
