Features provided by Juniper SRX:

Firewall User Authentication
It provides a layer of protection in the network. It restricts and permits users individually or sometimes in groups.
It is also known to protect the network. It protects the network by controlling who can access this network and how. It reduces policy management complexity with user-based and role-based firewall controls.
Intrusion Prevention
You can selectively enforce various attack detection and prevention techniques on network traffic passing through an IDP-enabled device.
IDP protects against network-based exploit attacks aimed at application vulnerabilities.
AppSecure is a suite of application security capabilities that identifies applications for greater visibility. It utilizes advanced application identification and classification to deliver greater visibility, enforcement, control, and protection over the network.

AppSecure detects application behaviors and weaknesses that prevent application-borne security threats that are difficult to detect and stop.

The following AppSecure service modules can be configured to monitor and control traffic for tracking, prioritization, access control, detection, and prevention based on the application ID of the traffic:

AppID – Provides application visibility and control over each application that is allowed to communicate on the network.
AppTrack – Simplifies application visibility and control.
AppFW – Stops users from visiting inappropriate web sites or inadvertently downloading spyware and other malicious applications from known sites.
AppQoS – Prioritizes traffic based on application type and limits the amount of bandwidth an application can consume.
SSL Proxy – SSL proxies provide encryption and decryption by residing between the server and the client. With the implementation of SSL proxy, AppID can identify applications encrypted in SSL. SSL proxy can be enabled as an application service in a regular firewall policy rule. IDP, application firewall, and application tracking services can use the decrypted content from SSL proxy.
UTM enables a business to protect itself from spam, viruses, worms, spyware, trojans, and malware. With UTM, you can implement a comprehensive set of security features that include:

Antispam – This protects against malware at the desktop, gateway, and server levels.

Web filtering–Web filtering stop users from visiting inappropriate websites or inadvertently downloading spyware and other malicious applications from known sites and ensures productivity and policy compliance.

Antivirus – This prevents spam messages and malicious content.

Content filtering – Content filtering provides basic data loss prevention functionality.

Layer 7 traffic classification and control

The Cisco Meraki Proprietary Packet performs Analysis of Network Traffic up to the 7th layer. Sophisticated Fingerprinting plays a vital role in this analysis. This fingerprinting helps in identifying new users, content, and applications. Network Flows are categorized, and Access Control Policies are applied. For example, Block Netflix and Prioritize Video Conferencing. The classification of traffic at layer 7 helps the Cisco Firewall to control encrypted, evasive, and peer-to-peer applications like Skype and BitTorrent. A traditional firewall cannot handle these issues. All wireless access points and security appliances include Cisco Meraki Next-Generation Firewall Intrusion Detection Engine.

Cisco Meraki Security Appliances work on protecting the network against malicious viruses and threats. It features the Sourcefire’s Snort, which is an integrated intrusion detection and prevention (IDS/IPS) engine. Sourcefire’s Snort is the single most widely deployed intrusion detecting and protecting in the world. Network Security can be maintained using a combination of signature, protocol, and anomaly-based inspection methods. Security is always up-to-date since signatures are automatically updated. Identity-based and Device-aware Security

The Device Aware Access Controls enable the administrators to make sure that the appropriate level is network access is provided for each class of devices. Apple iOS, Windows, Android, Mac OS, etc. are automatically detected and classified by Layer 7 device fingerprints. Post integration of fingerprints into Cisco Meraki Firewalls and Wireless APs administrators can use a Bring Your Own Device (BYOD) Network to which the firewall rules will be applicable.

Another very appealing feature of Cisco Meraki includes a powerful category-based content filter. This content filter matches content against millions of URLs in dozens of categories. For the content and application changes to align with security policies, these lists and application signatures are updated from the cloud.
