Network Security

Palo Alto Networks Next-Generation Firewall is a next-generation firewall platform that analyses network traffic not by port and protocol alone, but by application, user, content and threat context. It delivers application control, IPS, URL filtering, malware prevention, SSL inspection, DNS security and advanced threat prevention in physical, virtual and cloud form factors.

Detailed visibility of applications and users makes it possible to apply precise policies matched to business need, rather than broad network permissions. Bringing several security functions together under the same policy and management structure reduces operational complexity. The organization can stop known and unknown threats at the network layer, strengthen segmentation, and provide consistent security across data centre, branch and cloud environments.

Prisma Access ZTNA is a cloud-based Zero Trust Network Access solution that lets users reach private and cloud applications on the basis of identity, device posture and continuous risk assessment, regardless of where they are. Instead of the broad network access a traditional VPN provides, it connects the user only to the application they are authorized for and monitors the level of trust throughout the session.

Application-level access limits the ability of a compromised account or device to move laterally within the network. Providing a common access model for remote workers, contractors and branches reduces the complexity of VPN infrastructure. Central policy and cloud scale allow new users and applications to be brought online faster, improve the access experience, and make the Zero Trust strategy measurably enforceable.

Prisma Access Browser is a secure enterprise browser that governs access to corporate applications and data directly at the browser layer. On managed or personal devices it protects SaaS and web applications by controlling actions such as copying, downloading, printing, taking screenshots, uploading files and using extensions according to identity, device and data context.

Browser-based control helps provide secure access without installing a full management agent on the device — particularly useful in BYOD, contractor and merger-and-acquisition scenarios. Corporate data is separated from personal use, reducing the chance of sensitive data persisting on the device or being moved through unauthorized channels. Because it offers fast access without disrupting the user experience, it supports the business while, in certain scenarios, reducing the need for more costly approaches such as VDI.

Palo Alto Networks Next-Generation CASB is a cloud access security solution that discovers, risk-rates and controls users' interaction with SaaS applications and cloud services through security policies. With shadow IT visibility, application risk analysis, inline and API-based control, data protection and malware prevention, it covers both managed and unmanaged cloud use.

The organization can see centrally which cloud applications are in use and what data is being shared in them. Risky applications can be blocked or redirected to safe alternatives, and rules on downloading and sharing data can be enforced in approved SaaS services. This visibility reduces shadow IT and data leakage risk without halting cloud adoption, and establishes a controlled model of SaaS use across security, compliance and business teams.
