PRODUCT OVERVIEW

3 reasons why to choose PRTG as your Cisco ASA monitoring tool

Of course, monitoring your Cisco ASA firewall is important… But it can be a real pain when you must go through all generated logs manually and use CLI commands to filter the results. Paessler PRTG is designed to make your life easier with automated monitoring that helps you keep your network secure and performant.

network traffic

Better understand traffic with NetFlow

What do Cisco ASA and PRTG have in common? They both support NetFlow natively, which makes it easy to monitor the network traffic on your Cisco ASA devices with PRTG’s preconfigured NetFlow sensors. 

They can help you spot bandwidth bottlenecks or unusual traffic patterns that could indicate a security breach.

malicious activity

Monitor everything for malicious activities

PRTG gives you a clear view of what’s going on inside your network. It keeps an eye on how your Cisco ASA firewalls are performing and lets you know immediately if there are any issues. 

You can track VPN connections and user activity with the dedicated Cisco ASA sensors to easily spot unusual behavior. This way, you are able to quickly respond to potential security threats.

insights

Get insights into Cisco ASA with syslogs

When your Cisco ASA devices send syslog messages, you can count on PRTG to help you analyze these syslogs effectively with its native Syslog Receiver sensor. 

This makes it easier for you to investigate incidents and comply with your organization’s security policies. You can also use PRTG to analyze syslog data and troubleshoot issues like IP conflicts or authentication problems. Get a clear view on the performance of your firewalls.

What Cisco ASA monitoring looks like in PRTG

Diagnose network issues by continuously tracking your Cisco ASA firewalls and applications. Show bandwidth usage, CPU load, available memory, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot all kinds of security and performance issues.

Top features for effectively monitoring Cisco ASA devices with PRTG

test

Real-time traffic analysis

If you want to keep your network secure and perform well, real-time traffic analysis is an essential tool for you to have. 

PRTG provides you with live traffic data via SNMP, NetFlow, IPFIX, and packet sniffing to track bandwidth usage, discover anomalies, and find out where to take a closer look and what to do to optimize performance.

alerts and notifications

Custom alerts & notifications

Automated alerts are a must-have for any modern network monitoring environment. Set up custom notifications to flag critical events while avoiding false positives, so you’re always informed about anything that needs your immediate attention. 

This helps you zoom in on the areas that need more investigation or debugging, reducing unnecessary and costly downtime.

reporting

Individual reporting & dashboards

Create your own dashboards to see everything that you want to know about your network’s health and performance at a glance. 

Use PRTG’s historical data and generate reports that fit the needs of different stakeholders, from IT teams to management, to analyze trends. This way, you can make informed decisions about where to optimize your LAN, WAN, VLAN, or VPN.

PRODUCT OVERVIEW

“Our objective was to be able to monitor the health of our most critical servers containing data and applications, but also the flows and bandwidth between headquarters, our 50 servers in the cloud and the 15 servers at our production sites. For us, it is essential to have a proactive approach to understand where the weaknesses of the IT system are to be able to improve them.”

Marc Boullier, CIO
Carambar & Co

“From a server perspective, we're monitoring all of the key components of our service such as CPU usage, RAM disk space, the Windows services that it's running, and network connectivity of that server. In terms of networks, we’re monitoring all of our switches, firewalls, and access points. It’s really useful to be able to easily pull performance metrics from the PRTG dashboard.”

Ollie Kerslake, Infrastructure Lead
Riverford Organic Farmers

“The tool has given us greater control over all types of devices connected to the network (switches, IP telephony, security cameras, IoT, WiFi) that previously remained opaque when dealing with service incidents. This has improved our ability to diagnose and resolve problems, which has translated into greater efficiency and a better user experience in both internal and public services.”

Jordi Tolosà Bel, New Technologies Technician

Cisco ASA Monitoring: FAQ

 

What is Cisco ASA?

Cisco ASA (Adaptive Security Appliance) is a series of enterprise-grade firewalls that offer advanced security features like VPN support, intrusion prevention, and advanced malware protection. Cisco ASA devices are widely used to protect network infrastructure from both internal and external threats.

Why does Cisco ASA need continuous monitoring?

Monitoring Cisco ASA helps keep your network secure and perform at its best. With lots of traffic, changes to settings, and new threats, monitoring helps find and fix problems quickly. This keeps your firewall strong against new cyber threats.

What is a failover link and why is it important for high availability?

A failover link is a dedicated connection between two Cisco ASA devices that enables them to share critical information, such as session details and configurations, to maintain network security and performance. The ASDM (Adaptive Security Device Manager) or CLI (Command Line Interface) can be used to configure interfaces and IP addresses for these links. 

Failover links are vital for high availability because they ensure that if the active unit fails, the standby unit can immediately take over as a last failover, maintaining continuous service and minimizing disruptions in network connectivity.

Are there best practices for setting up failover links?

To get the best performance and reliability from your Cisco ASA, you need to set up failover links correctly. Use dedicated interfaces for the failover links to avoid congestion and enable high-speed data transfer. Also, use different IP addresses for the failover links to avoid conflicts and ensure smooth operation. 

Testing the failover configuration regularly ensures it works correctly and allows for a seamless switch to a standby device in case of a failure. Monitoring the status of failover links with monitoring software like Paessler PRTG continuously helps detect potential issues early on, while keeping a detailed record of all configurations and changes facilitates a quick and smooth recovery from any network disruptions.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
