Description

The global email security market is entering an accelerated phase of transformation, driven by AI-intensified threats, architectural convergence, and rising regulatory scrutiny across all major regions. From 2023 to 2028, the industry will expand from $6.07 billion to more than $11.1 billion, as organizations overhaul legacy defenses and shift toward unified communication and security platforms that protect email, collaboration, and browser channels. Generative and multimodal AI now power both attack and defense, reshaping expectations for detection efficacy and driving demand for explainable, privacy-preserving models, especially in EMEA, where sovereignty mandates and NIS2/DORA enforcement are setting global benchmarks for compliance-aligned architectures. At the same time, hybrid and API-native deployments, including emerging inline pre-delivery approaches, are accelerating migrations away from traditional gateways and enabling flexible modernization without operational disruption. Growth opportunities will be strongest in 3 areas: convergence across communication channels, MSP-led delivery for SMB and mid-market customers, and AI-driven automation that reduces SOC workload and proves measurable ROI. As competitive intensity increases and native Microsoft 365/Google defenses elevate the baseline, vendors that deliver unified platforms, transparent AI pipelines, regional data-residency options, and outcome-based value will capture the next wave of global revenue. This study identifies where future innovation and commercial momentum will emerge, providing a strategic roadmap to help industry participants align technology, go-to-market execution, and ecosystem partnerships with the most impactful opportunities in the evolving email security landscape.

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
