Users are accessing cloud applications from anywhere at any time, which has expanded the attack surface and made network defenses more difficult. Traditional network protections are overwhelmed by modern threats like encrypted web traffic and 700+ new browser vulnerabilities each year. Half of malware in 2019 will use encryption for delivery, command and control, or data exfiltration, hiding threats from security tools. Symantec Web Security Services provides cloud-based network security that balances security, performance, complexity and cost to address these challenges.
