PRTG in 2025: A Look Back at Another Year of Innovation

Six Releases That Kept Things Moving

Let's start with the numbers, because they tell a story on their own. We rolled out six stable releases throughout the year, each one bringing something new to improve your monitoring experience.

Throughout the year, every release was like opening a little present. Some brought shiny new features, others fixed those annoying little bugs you'd reported, and a few delivered both. From early January to the final release in December, we kept the momentum going.

Here's what made these releases special:

📌 Version 25.1.104 kicked things off with Audit Logging for PRTG Subscription customers - because sometimes you just need to know who changed what and when. We also introduced Single Sign-On via the new UI and API v2, making life easier for those of you managing large teams. New sensors like the Cisco WLC Access Point Overview sensor and PRTG Data Hub sensors graduated from BETA status.

📌 Version 25.2.106 brought sensor migrations and better device templates. The Script v2 sensor got support for native executables, which opened up a whole new world of custom monitoring possibilities.

📌 With version 25.2.108, several sensors graduated from their BETA phase, including the SNMP UPS Status sensor. We also introduced the NATS Server Overview sensor and continued our journey of modernizing sensors with v2 versions compatible with the multi-platform probe.

 📌Version 25.3.110 saw the SSH Disk Free v2 and REST Custom v2 sensor leave BETA status. We also introduced the experimental REST JSON Data sensor for those who love working with APIs.

📌 Version 25.4.112 gave us the SNMP Linux Disk Free v2 sensor, expanded our API v2 capabilities, and updated sensor schemas for better control over monitoring thresholds.

📌 And finally, version 25.4.114 wrapped up the year by fixing important issues with the Windows Updates Status sensor and VMware Datastore sensor - because nobody wants their monitoring broken during the holiday season.

The Multi-Platform Probe Goes Industrial

Here's something that genuinely excited us this year: our multi-platform probe joined the Siemens Industrial Edge ecosystem.

We know, we know - it sounds technical. But think about it for a second. Manufacturing plants, production lines, industrial equipment... these environments have traditionally been tricky to monitor. Different protocols, different systems, and often a pretty big gap between IT and OT teams.

The multi-platform probe changes that game. It's lightweight, container-friendly, and can handle industrial protocols like OPC UA, Modbus TCP, and MQTT right alongside your standard SNMP monitoring. Deploying it on Linux, ARM devices, or Docker containers? No problem.

For customers in manufacturing and production environments, this integration meant they could finally get unified visibility across their entire operation. One customer reported 25% faster root cause identification after implementation. That's the kind of number that makes a real difference when production lines are on the line.

Visualizing Across Multiple Servers: Multi-Core Dashboards

If you're running PRTG Enterprise Monitor with multiple servers, you probably know the pain. Switching between instances, trying to get a unified view of your infrastructure, piecing together the big picture from multiple sources...

We heard you. That's why we made PRTG Multi-Core Dashboards available at no additional cost for PRTG Enterprise Monitor customers.

By pairing PRTG Data Exporter with Grafana, you can now create comprehensive dashboards that pull data from all your PRTG servers into one beautiful, unified view. Pre-built templates get you started quickly, but you can customize to your heart's content. Different teams need different views? No worries - create tailored dashboards for security teams, network teams, and executives, all from the same data.

This wasn't just another feature - it solved a real problem that enterprise customers had been asking about for a while. Finally, one place to see everything.

Security Front and Center

Let's talk about something that kept a lot of us up at night in 2025: security.

We published two important articles that highlighted how network monitoring isn't just about uptime anymore - it's a critical part of your security strategy.

Detecting exploitation became a hot topic as the average time-to-exploit dropped to just 5 days in 2024. When vulnerabilities are announced, attackers move fast. Really fast. Network monitoring can catch the anomalies - those unusual DNS queries, unexpected outbound connections, CPU spikes - that might indicate someone's already in.

And then there's vulnerability management. With Windows 10 reaching end of support in October 2025, this became more relevant than ever. Keeping systems updated isn't just good practice - it's essential for security and compliance.

PRTG's flow sensors, SNMP traffic monitoring, and system health checks all play a role in detecting when something's off, even before traditional security tools catch it.

Your 8-Week Journey to PRTG Mastery

Okay, we'll admit - this was one of our favorite projects of the year.

We launched an 8-week series designed to take you from basic monitoring to PRTG mastery, one week at a time. Whether you're brand new to PRTG or you've been using it for years but suspect you're missing some tricks, this series had something for you.

Each week tackled a specific challenge:

📅 Week 1 made sure you're actually monitoring everything that matters. Auto-discovery is great, but are you 100% sure every critical device is being watched?

📅 Week 2 moved beyond simple up/down checks to vendor-specific sensors that give you real insights.

📅 Week 3 opened up the PRTG Sensor Hub, showing you how third-party sensors and templates can monitor systems you didn't even know were possible.

📅 Week 4 was all about notifications - because monitoring is pointless if you don't know when things go wrong.

📅 Week 5 taught you to organize with sensor libraries - because managing hundreds or thousands of sensors without a solid structure is a recipe for chaos.

📅 Week 6 showed you how to create dashboards and maps that actually help - not just pretty visualizations, but tools that give you real insights at a glance.

📅 Week 7 covered automated reporting so you can prove your worth to management without spending hours creating presentations every month.

📅 Week 8 wrapped it all up with optimization techniques - fine-tuning your setup for maximum performance and minimal resource usage.

The response was fantastic. People actually followed along week by week, implementing the lessons in their own environments. Some told us it transformed how they use PRTG.

Practical How-To's That Made Life Easier

Sometimes it's the little things that make the biggest difference.

We published several how-to guides this year that solved specific, practical problems:

Ever thought Synology was just for NAS? We showed you how to monitor their cameras too. Surveillance stations, disk health, camera connectivity - all monitored through PRTG.

Speaking of Synology, we also covered monitoring the DSM version. Sounds simple, but it's one of those things that's easy to overlook until you realize you're months behind on updates.

SNMPv3 configuration got a complete guide covering both Windows and Linux. Security matters, and SNMPv3 is the way to do SNMP right - with authentication and encryption.

And for those ready to level up their custom monitoring, we published a complete guide on transitioning to the Script v2 sensor. Better error handling, versioned output format, modern architecture - everything you need to write reliable custom scripts.

Level Up Your Skills: PRTG Training

Reading guides and articles is great - you're doing it right now. But sometimes you need more than documentation. Sometimes you need hands-on training from people who really know PRTG inside and out.

2025 was a busy year for our training team. We ran 44 PRTG training sessions across different time zones and experience levels, with 272 participants joining us to level up their monitoring skills. And here's what makes us really proud: 289 IT professionals earned their certification as PRTG Monitoring Experts throughout the year. Those aren't just numbers - they represent real people who invested in their skills and are now confidently managing complex monitoring environments.

What made these sessions special? They're led by our system engineers who know PRTG from the inside out. You're not just passively watching slides - you're actually working with PRTG, solving real-world scenarios, and getting answers to your specific questions. Whether you're just getting started or you're ready to master custom sensors and complex distributed setups, there's a training level that fits.

Can't make the scheduled dates? No worries. We arrange individual training sessions that fit your schedule. And if you're serious about proving your PRTG expertise, the Paessler Certified Program is waiting for you. Becoming a certified PRTG Monitoring Expert isn't just a nice credential - it validates your skills and gives you the confidence to tackle monitoring challenges that would've seemed daunting before. Join the growing community of certified professionals who've already made that leap in 2025.

When You Need More: Scaling Made Simple

Hit your sensor limit? We've all been there. Your network grows, you add more devices, suddenly you're at capacity and monitoring new systems means tough choices.

We made it easier. Our article on upgrading your PRTG license walked through the self-service upgrade process. A few clicks in the Paessler Portal, and you're back in business.

Plus, when you upgrade to larger editions, you unlock additional features like PRTG Data Hub, SLA Reporter, and PRTG Multiboard. More sensors, more capabilities - it just makes sense.

Looking Ahead

So that was 2025. Six releases, dozens of new sensors, major integrations, comprehensive guides, and continuous improvements to make your monitoring more powerful, more flexible, and more secure.

But here's the thing about PRTG - we're never really done. There's always another sensor to build, another integration to create, another problem to solve. Because your networks keep evolving, and PRTG evolves with them.

As we head into 2026, the development team is already working on what's next. New sensors? Absolutely. More integrations? You bet. Features you didn't even know you needed? Probably those too.

And here's something cool - you can actually shape what comes next. Over on Paessler User Voice, you can suggest new sensors, vote on features others have requested, and see what's already in the pipeline. Some of the best additions to PRTG came directly from user suggestions. Got an idea for a sensor that would make your life easier? We want to hear about it.

If you want to see what all this means for your environment, there's no better time to explore what PRTG can do. Download a free trial and see for yourself how far monitoring has come. Who knows - by this time next year, we might be writing about the innovations you helped inspire.

Here's to another year of keeping your networks running smoothly.
