The emails that you want are only the tip of the iceberg that you get.

Your Challenge
Within the email security gateway (ESG) marketplace, there are numerous vendors with varying options who all claim to be the perfect fit for your organization. It becomes challenging to sift through all the offerings and find the right one.
An ESG must serve a multitude of functions for the organization, as well as meet an array of requirements, all of which can be hard to accurately assess and include confidently.
IT security always struggles with costs. An email gateway can become expensive, but it is vital and thus needs to have a strong case made for implementation, improvement, or replacement scenarios.

Our Advice

Critical Insight
Cloud adoption among business functions is already high. Moving email to the cloud is just another step. Take this into consideration when selecting an ESG.
Advanced Persistent Threats (APTs) and Zero-Day attacks are changing the way organizations deal with threats. Recognize the need for greater visibility and tools that stay current with these developments.

Impact and Result
Understand developments within the ESG market to properly evaluate all capabilities and functions of an ESG.
Evaluate ESG vendors and products based on your enterprise requirements.
Determine which products are most appropriate for particular use cases and scenarios.

Vendor Landscape: Email Security Gateway Presentation Transcript

  • 1. Key Insight: Cloud adoption among many business functions, including email, is pushing organizations to consider ESG cloud or hosted based deployments. Due to increased targeted attacks originating from emails, increased malware detection, behavioral analysis, and traffic visibility is needed to combat these new threats. Timeline Information: How did we get here? Email Security Gateways developed steadily over the 2000s in reaction to the increase in spam and other unwanted emails, as well as new email-based threat developments. Development of authentication methods, machine learning, blacklisting, whitelisting, and content filtering moved from the frontier defenses of ESGs to necessary stakes. The number of market competitors decreased due to the need for large intelligence gathering capabilities to stay up to date on the latest threats and attack campaigns. Proliferation of botnets to create zombie attacks as well as to compromise whitelisted domains underscore the need for active content filtering and behavioral analysis. The recent development of spear phishing (targeted email attacks) has resurged the need for ESGs to protect against the most costly of user credential compromise or intellectual property theft. Understand where we are now: Get it out to the cloud Cloud adoption among business functions is already high. Moving email to the cloud is just another step. Take this into consideration when selecting an ESG. The professional attack Attacks are advancing day in and day out. Advanced Persistent Threats (APTs) and Zero-Day attacks are changing the way organizations deal with threats. Recognize the need for greater visibility and tools that stay on top of these developments. Know where we are going: The threat landscape is becoming more advanced, fast paced, and reactive with more persistent adversaries. Traditional mass attacks and general spam are still a huge concern and nuisance. The proliferation of spear phishing, either by criminal organizations, hacktivist groups, or state sponsored groups, is developing into a standard attack method with commodity style markets selling and reselling these techniques. Vendors are placing a focus on integrated security solutions so that incoming and outgoing traffic across internet, email, and other streams can be analyzed across mediums with multiple tools to detect unidentified attacks. This can include integration with DLP, SIEM, IDPS, firewalls, and other security solution products. There is a general development by cloud ESG providers to become more robust in their offerings to meet the general market push by organizations to move to the cloud with other functions.
