Network audit checklist for IT infrastructure security
I've seen this scenario play out countless times - companies investing in security only after a breach has already cost them dearly. It's like frantically patching servers after ransomware has already encrypted your customer database. Reactive security isn't really security at all. Here's the truth about network audits: they're not just bureaucratic paperwork. A solid audit checklist is your blueprint for actually protecting your infrastructure against the threats that keep IT directors up at night.
Unlock the hidden potential of PRTG: Join our exclusive live webinar
Are you using PRTG to its full potential? Join us for an upcoming webinar that will take your monitoring capabilities to the next level. On Tuesday, June 3, 2025, our product experts will present exciting use cases that go beyond traditional IT monitoring.
IOPS vs Throughput - What you need to know for optimal storage performance
When your business-critical applications slow to a crawl, storage performance is almost always the hidden culprit. But here's the challenge: fixing the real problem means understanding two distinct metrics - IOPS (Input/Output Operations Per Second) and throughput (data transfer rate). Get this wrong, and you'll waste significant budget on storage solutions that don't actually address your bottlenecks. Even worse, your users will continue facing those frustrating delays that impact productivity and revenue.
PRTG version 25.2.106 is out now!
A new PRTG stable release is here! Version 25.2.106 brings a mix of new features, improvements, fixes, and some important updates to enhance your monitoring experience.
Effortless monitoring coverage: Discovering gaps with sensor recommendations in Paessler PRTG
Introduction: The monitoring challenge - noise vs. blind spots In the complex world of IT infrastructure, monitoring itself is often presents a double-edged sword. IT professionals can find themselves drowning in alerts from non-critical systems (noise) or, perhaps worse, feeling safe despite having significant blind spots where critical performance issues or failures go completely unnoticed. Paessler PRTG is designed to simplify IT monitoring, and one key feature directly tackles the challenge of ensuring comprehensive coverage without manual guesswork: Automated Sensor Recommendations.
Data center capacity planning - A guide for IT infrastructure teams
Ever had that sinking feeling when your boss asks if the data center can handle next quarter's big product launch? Data center capacity planning isn't just an IT checkbox - it's what keeps your physical infrastructure running when workload demands spike and executives start asking uncomfortable questions.
How to find IP addresses on your network: A complete guide for IT leaders
Ever had that moment when the CEO calls at 7 AM because "the internet is down," and you're frantically trying to figure out which of your 500+ network devices is causing the problem? Been there. 🫡 Finding and managing IP addresses across your network isn't just some technical checkbox - it's the difference between being the IT hero who resolves issues before users notice and the person explaining to executives why email was down for three hours.
How Network Discovery strengthens your cybersecurity risk assessment
You can't defend what you don't know exists - that's the brutal truth facing IT teams today. With a shocking 60% of breaches involving network devices that fly under IT's radar, the invisible parts of your network infrastructure are likely your biggest vulnerability. And the costs? Devastating: downtime, data theft, regulatory fines, and that nightmare call to your CEO.
Database security best practices for protecting critical data assets
Think your database is secure because you've got a decent firewall and strong passwords? Think again. I've watched database security best practices completely change over the last few years - mostly because hackers got a whole lot better at their jobs (while we were busy in meetings, probably 🙊). It's kinda scary how easily they slip past firewalls these days. They love finding those little goldmines like the SQL Server you forgot to patch last month, or those admin accounts with way too many permissions that nobody's reviewed since 2019.
Streamline your monitoring: Paessler AI tackles sensor similarity & reduces complexity
Keeping your IT monitoring efficient and insightful can feel like a constant battle. Tuning thresholds, managing alerts, and deciding precisely what and how to monitor requires ongoing effort. One common challenge is the accidental creation of redundant or very similar monitoring sensors, cluttering your view and potentially wasting resources. Agentless monitoring tools like PRTG offer a significant advantage here, allowing for Auto discovery and monitoring adjustments without needing to deploy new software everywhere. This ease of use is central to PRTG's approach.
Thin vs Thick Provisioning - Making the right storage choice for your IT infrastructure
Ever stared at the "Disk Provisioning" dropdown when creating a new VM and wondered if it really matters? Trust me, it does. I've spent countless hours dealing with the aftermath of hasty storage decisions, and the choice between thin and thick provisioning can make or break your infrastructure's performance and stability.
All you need to know about the latest PRTG release 25.1.104
A new PRTG release is now available in the stable release channel. This release includes the new Audit Logging feature for PRTG Subscription, default installation of the PRTG application server for new PRTG installations, new sensors like Cisco WLC Access Point Overview sensor, Port v2, SSH INodes Free v2 and PRTG Data Hub as well as an update of the German and Spanish language files.
What are database performance metrics? (and why your SQL queries cry at night)
If databases had therapy sessions, performance metrics would be the therapist's notebook - a brutally honest summary of everything that’s going wrong (and occasionally, what’s going right). Whether you're running Oracle, PostgreSQL, MySQL, or SQL Server, your database performance metrics are the pulse of your entire data infrastructure. And if you’re a seasoned sysadmin, you know that when things go south, it's rarely a polite descent - it’s more of a flaming rollercoaster into bottleneck hell.
Network assessment - Build a stronger and more efficient IT infrastructure
Ever had your network crash during a crucial client presentation? Or discovered a cybersecurity breach that had been lurking for months? Not fun.
Understanding the differences between LDAP and AD
When protocols walk into a bar... An LDAP server and an Active Directory domain controller walk into a bar. LDAP orders a gin - no tonic, no ice, just neat. AD asks for a custom-built cocktail with user authentication, group policy, and a slice of Kerberos on top. The bartender, who looks suspiciously like a stressed-out sysadmin, mutters something about directory dependencies and walks away. If you've been managing user accounts in hybrid IT infrastructures for a few years, you’ve probably crossed paths with both LDAP and Microsoft Active Directory. Maybe you've tried to deploy OpenLDAP in a Linux-based environment or struggled with group policy quirks in a Windows Server setup. Either way, the LDAP vs. AD question is a classic, especially when authentication, permissions, and identity and access management (IAM) come into play.
