Palo Alto Networks launches Nebula for network security

By Shannon Williams
Thu 10 Feb 2022

Palo Alto Networks has announced the release of Nebula, the latest upgrade of its PAN-OS software, to help find the evasive, zero-day attacks that can cripple organisations and stop them in their tracks. 

PAN-OS 10.2 Nebula collects, analyses and interprets potential zero-day threats in real time using inline deep learning a network security first. This results in six times faster prevention and 48% more evasive threats detected, surpassing anything previously available. 

Nebula also introduces AIOps Palo Alto Networks tenth security service and the new Advanced Threat Prevention service while enhancing Advanced URL Filtering, DNS Security, IoT Security and other related security services.

"In the past, nation-state-led cyberattacks were considered the rarest and most advanced. But today, attackers of all kinds have an advanced arsenal at their fingertips; every organisation must now assume they will be the target of a nation-state-level attack," says Lee Klarich, chief product officer, Palo Alto Networks. 

"Modern network security requires a fundamentally new approach. Today, Palo Alto Networks has brought that new approach to our ML-Powered Next-Generation Firewalls by harnessing the processing power of the cloud to enable deep learning inline. We believe that is how all network security will be done in the future."

Security services that are being added and enhanced include:

Advanced Threat Prevention
A new best-in-class intrusion prevention system (IPS), which brings security analysis from offline to inline using cloud compute for AI and deep learning techniques without sacrificing performance. Advanced Threat Prevention can detect many unknown and targeted command and control (C2) attacks as well as evasive attacks from tools such as Cobalt Strike.

AIOps
The new AIOps uses machine learning to predict up to 51% of disruptions to NGFWs before they impact the firewalls. In addition, with telemetry from over 6,000 deployments, AIOps continuously recommends best practices to improve overall security posture.

DNS Security
Now extends protection for the latest DNS-based attack techniques, including strategically aged domains, making it the most comprehensive DNS security solution available with 40% more DNS-based threat coverage than other leading vendors.

Advanced URL Filtering
Adds prevention of new, highly evasive phishing attacks, ransomware and other web-based attacks through deep learning-powered analysis of web traffic now including live web content in real time and inline.

IoT Security 2.0
Simplifies IoT device visibility and automates policy creation across seen and unseen devices by using machine learning.

"Security approaches are too often reliant on an initial victim being exploited. Yet, with attackers as agile and efficient as they are today, organisations require real-time prevention to protect their environments," sats John Grady, senior analyst at the Enterprise Strategy Group.

"Palo Alto Networks recognises these issues and is expanding its machine learning capabilities by placing Deep Learning detection inline to prevent attacks before they ever impact victim one."

Rajarshi Dhar, industry analyst, Frost & Sullivan, adds, "Palo Alto Networks industry-leading machine learning-based platform applies techniques that help customers handle sophisticated threats and meet end-to-end demands across network, endpoint, and cloud security. 

"The company enables enterprises to go beyond standard threat protection by building a strong security posture and resilience."
