    IDC MarketScape IDC MarketScape: Worldwide Web Security 2016 Vendor Assessment Robert Westervelt Elizabeth Corr IDC MARKETSCAPE FIGURE FIGURE 1 IDC MarketScape Worldwide Web Security Vendor Assessment Source: IDC, 2016 Please see the Appendix for detailed methodology, market definition, and scoring criteria. March 2016, IDC #US41000015 IDC OPINION The Web security market is in a state of transition as organizations race to identify and extend control and visibility to a significantly growing mobile workforce. Web security vendors are also adapting to extend visibility and control over software-as-a-service (SaaS)–based services, which can be easily adopted by employees through their mobile devices to support file sharing and collaboration. The rapidly evolving threat landscape is also forcing Web security gateway makers to catch up with more powerful offerings. Criminal attack campaigns target users through Web site drive-by attacks, often from legitimate Web sites, where malicious code scans Web browsers and browser components to exploit Flash and Java vulnerabilities. These risks have led to highly visible threats, including a continued barrage of banking malware. Attacks are increasingly being delivered via hijacked advertising networks, weaponizing legitimate sites where the ads are hosted. Ransomware is also being detected in greater amounts and can spread through a drive-by attack, links shared on social media sites, or through malicious files hosted on popular SaaS services. Organizations are seeking more robust Web security capabilities. Web security deployment models are rapidly changing as organizations address how to enforce security policies on remote workers, branch offices, and mobile devices. The standard on-premises approach is one of three main deployment options available to customers, but SaaS and hybrid deployment models are increasingly being adopted.

    Magic Quadrant for Secure Web Gateway Gartner RAS Core Research Note G00160130, Peter Firstbrook, Lawrence Orans, 11 September 2008 R2860 09172009 Secure Web gateway solutions protect Web-surfing PCs from infection and enforce company policies. Incumbent providers have been slow to respond to changing demands, while new vendors are struggling to get the right product mix and prove their mettle in the demanding enterprise market. WHAT YOU NEED TO KNOW This document was revised on 16 September 2008. For more information, see the Corrections page on gartner.com. • Organizations need to purchase a strategic product that has a road map coinciding with long-term needs – which would mean sacrificing current functionality – or accept a tactical solution that solves current needs and will likely need to be replaced in the midterm to long term. • If URL-filtering reporting is a key requirement, then traditional URL-filtering vendors represent the best choice. • Given that malicious software (malware) filtering is a key requirement, products must offer proactive “zero day” malware detection techniques that do not rely on previous knowledge of the malware, as well as signature-based detection techniques. Products should inspect bidirectional Layer 4 through Layer 7 network traffic across all ports and protocols. • Application control is the least-mature secure Web gateway (SWG) feature. • Large enterprises will have a smaller field of candidates to select from because of scalability and reliability demands. MAGIC QUADRANT Market Overview An SWG is a solution that filters unwanted software/malware from user-initiated Web/Internet traffic and enforces corporate and regulatory policy compliance. To achieve this goal, SWGs must, at a minimum, include URL filtering, malicious-code detection and filtering, and application controls for popular Web-based applications, such as instant messaging (IM) and Skype.
