Symantec and Norton Security Solutions Win AV-TEST Institute Best Protection Awards for Third Consecutive Year

Only Company to Win Enterprise and Consumer Best Protection Awards Across all Platforms Tested, Blocking Every Attempted Attack in Testing

MOUNTAIN VIEW, Calif., Mar. 21, 2018 – Symantec Corp. (NASDAQ: SYMC), the world's leading cyber security company, today announced that Symantec won AV TEST's prestigious Best Protection award for all four platforms tested – Norton Security, Symantec Endpoint Protection, Symantec Endpoint Protection Cloud, and Norton Mobile Security. With the highest score for each product in its respective test category, Symantec's protection products lead the pack for consumer and enterprise products on Windows, Mac and Android.

AV-TEST Institute is globally recognized for its rigorous independent testing practices, evaluating the efficacy of endpoint security solutions against advanced attacks throughout the year. The organization subjects each security solution to more than 1,000 live zero-day attacks delivered via infected websites and emails, and over 65,000 current and widespread threats. AV-TEST uses entirely new attacks each month to ensure attackers' attempts to evade protection are fully tested.

In each of AV-TEST's 6 certification tests, Symantec and Norton blocked every single attack – there was not a single miss. The nearest competitor missed five current and widespread threats.

"In 2017, Symantec completely convinced the testers with overall best protection across all software platforms. Whether Windows, macOS or Android, Symantec security solutions offer optimal protection for consumers and enterprises," said Andreas Marx, CEO, AV-TEST. "When it comes to effective protection, Symantec was head and shoulders above the competition in this year's testing. It's truly a great achievement to win Best Protection across all platforms and we commend the company for receiving this distinction."

Symantec Endpoint Protection (SEP) is Symantec's flagship enterprise endpoint security solution, delivering unrivaled protection, detection and response, meeting the advanced security requirements of the cloud generation in a single, easy-to-use agent. It combines new advanced features including deception technology, mobile threat defense via SEP Mobile, integrated endpoint detection and response, machine learning and zero-day exploit protection, and application isolation with SEP Hardening. SEP Cloud offers the same best-in-class protection as SEP in an easy-to-use security-as-a-service option for organizations with limited IT security resources.

Norton Security, Symantec's flagship consumer security solution safeguards users' devices and private information from today's most aggressive threats and ransomware. Multi-layered protection technologies, with the addition of advanced machine learning, artificial intelligence and new zero-day exploit protection proactively identify at-risk files and stop zero-day threats without slowing down a machine's performance. Norton Mobile Security provides proactive protection for smartphones and tablets to safeguard online privacy and protect against digital threats like risky apps.

Both enterprise and consumer solutions bested 24 competitive products in all of AV-TEST's protection categories for the third year in a row, representing superior protection amongst competitors.

"AV-TEST uses real zero-day attacks, not previously-seen samples, just as consumer and enterprise customers experience them," said Adam Bromwich, senior vice president, Symantec Security Technology and Response. "Symantec's leadership in the Best Protection category for three years in a row is the result of significant investment in new technology and our passion for keeping our customers and their data safe. We're proud to lead the way in protection for consumers and enterprises alike."
