iSheriff Web Security is a cloud-based Internet filtering and Web 2.0 security service. It provides your users with a safe and secure Internet connection, protected from threats and malware, while ensuring that Web browsing is appropriate and complies with your acceptable use policies.

Why do I need Web Security?

Web 2.0 has transformed Internet use from a once static resource into a rich and dynamic collaboration experience. Unlike the past where Websites were tightly controlled, the content of many of today’s Websites - like Facebook and YouTube - relies on the contributions of millions of Internet users. The negative effect of this change is that organizations can no longer implicitly trust supposedly ‘legitimate’ sites as safe and free of malicious content.

Traditional Web security solutions such as URL filtering and signature based anti-virus, while still important, are no longer effective protection on their own. The Web 2.0 environment demands realtime protection which can analyze continuously evolving Web content and keep pace with Web-based applications in a constant state of flux.

Incoming Web threats are not the only concern. With millions of Web users now actively contributing Web content through ‘tweets’, blogs, webmail, video and social networking sites, organizations need to be monitoring their outbound Web content now more than ever. Most organizations place a special significance on their intellectual property and sensitive data which is susceptible to data leakage via the Web. You need to be certain that Internet use is safe, secure, productive and appropriate..

Malware Protection

Today’s Internet environment presents organizations with a new set of dynamic security challenges. Effective Internet security solutions must be able to analyze Internet content in real-time and reliably assess the nature of that content. This is especially true of Web-borne threats.

Traditional anti-malware solutions, which rely on constant and timely updates to remain effective, are insufficient against the latest Internet security threats. iSheriff applies a cohesive, multi-faceted approach to Web threats by employing multiple layers of security in a unique three-stage approach:

threat analyzer


iSheriff Web Security employs a patented dynamic data modeling engine to analyze and predict the presence of malicious code and browser exploits.

  • Real-time detection of active code anomalies
  • Traffic monitoring, analysis and benchmarking to detect changing patterns
  • Data modeling compares data patterns against known models to ensure authenticity
  • Active behavioural analysis of site content
  • All data modeling and real-time content analysis is performed in over a dozen languages


iSheriff actively blocks Web threats in real-time by using data correlation across Web, endpoint and email vectors for millions of users around the world.

  • MIME-based identification of file types to prevent download or activation of misrepresented files
  • Dynamic classification of Web content means that once Web content is identified as a threat, it is blocked immediately
  • Real-time correlation of threat intelligence across Web and email traffic, and endpoint behavior
  • iSheriff dynamically accesses the status of URLs and prevents access to infected portions of popular Websites


iSheriff threat analysis is extremely fast, providing complete content analysis in microseconds and no discernable delay in delivery of Web content.

  • High performance malware scanning is applied to reliably detect known malware
  • Code analysis of suspicious files reveals potentially malicious activity
  • Outbound connections are constantly monitored and traffic to known botnet servers is disrupted and reported on

Off-network Protection

More often than not, today’s users are accessing the Internet from outside the safe confines of the corporate network. The reality is that remote users are typically no longer bound by VPN or MPLS restrictions.

In fact, many businesses have moved their IT infrastructure entirely to the cloud, eliminating the concept of the network perimeter altogether. This means that devices are wide open to infection, putting the sensitive applications and files they are accessing at a significant risk of being compromised.

iSheriff solves this problem by delivering complete security protection for users and their devices outside of the network perimeter, regardless of their location around the globe. iSheriff operates the world’s largest cloud security network, comprising 25 data centers that ensure global redundancy and scalability.

The iSheriff data centers are connected to our global private backbone network, with over 1,000 points of access around the globe. The iSheriff endpoint client automatically detects whether a device is on or off the network, automatically routing the user to the nearest access point and ensuring the highest level of performance.

Data Leakage Prevention

iSheriff enforces content policies to ensure that sensitive data does not leave your organization through the Web or via email. Policy choices include Payment Card Industry (PCI-DSS), Private Health Information (PHI), Social Security Data and Personally Identifiable Information (PII).

Certain file types and extensions may be specified for blocking on an outbound or inbound basis. Protection can also be enforced across HTTPS connections.

Policies can be configured with a couple of clicks, and then they’re automatically enforced across designated user groups through all email and Web activities.

The iSheriff cloud scans all outgoing and incoming data to automatically enforce data policies, blocking and reporting on any attempted transmissions of sensitive information.
