Security Researcher – Threat Data Analyst

Zscaler, the innovator and market leader of in-the-cloud security solutions, is building a world-class security research team in Bangalore, India. We are looking for self-motivated individuals with innovative ideas to identify and develop unique approaches for implementing protective web security measures in a cloud based (a.k.a. “software as a service”) security model. Threats are more dynamic and complex than ever before and traditional security approaches no longer suffice. We are moving security from the LAN to the cloud but it will take innovative approaches conceived by brilliant minds to get there.


The Security Researcher – Threat Analyst, will be responsible for conducting (big) data mining to identify emerging threats leveraging Zscaler’s cloud based infrastructure. The Threat Analyst must thrive on combing through millions of network logs to identify the needles in a haystack – the attacks that aren’t yet known. Responsibilities will include leveraging existing Zscaler (big) data mining tools, developing unique tools and utilizing them to automate the identification of threats that will then be used to develop new cloud based protections and for blogs and whitepapers delivered to the Zscaler customer base to illustrate the newly discovered threats.

To succeed in this role, the candidate must possess a strong technical knowledge of web-based threats, have truly impressive scripting skills and live to identify the next attack vector, no matter how deep it’s hidden. Responsibilities may also include conducting forward thinking research initiatives, which lead to deliverables such as blogging, whitepapers, speaking engagements and media appearances.


• Required 4+ years of security research experience.
• Proven track record of innovative ideas and an ability to implement them.
Strong understanding of the HTTP protocol and web application security.
• Strong scripting skills in Perl and Python.
• Strong writing skills and examples of past blogs, whitepapers, etc.
• Data mining experience with large security data sets such as IDS, IPS and firewall logs
Strong writing skills and examples of past blogs, whitepapers, etc.

• Publication of past research and/or speaking engagements.
• Experience writing IDS/IPS signatures.

Education Requirements:

• The candidate will have a bachelor’s or graduate degree from four-year college or university (preferably in Electrical/Computer Science, Engineering, or a related discipline), or equivalent security industry work experience.
