Only 13% of enterprises have enterprise-grade internal threat detection, while 29% can’t spot ransomware lurking on their network
In QNAP’s “Global Enterprise Cyber Resilience Survey 2026”, 1,838 organizations across 93 countries assessed their own cyber resilience. One question asked: if ransomware were already hiding on your network, moving laterally over SMB file shares and preparing to encrypt files, could your organization detect and stop it on its own? Only 13% have deployed network detection and response (NDR) at the network layer that can automatically detect and isolate the source of infection. At the other end, 29% admit they have no proactive detection at all, and typically realize they’ve been breached only when file extensions change or antivirus raises an alert.
The remaining 58% have endpoint detection and response (EDR) or firewalls in place, yet still can’t monitor every device on the internal network. That leaves blind spots where attackers can move laterally without IT ever seeing them.
Ransomware starts moving laterally within 29 minutes on average, yet intrusions take a median of 11 days to detect
Attacker speed (minutes): The CrowdStrike 2026 Global Threat Report found that eCrime groups need an average of just 29 minutes to move from initial access to lateral movement. That is 65% faster than in 2024, and the fastest case took only 27 seconds.
Defender speed (days): Google Mandiant’s M-Trends 2025 reports a median of 11 days from intrusion to detection, stretching to 26 days when an outside party is the one to raise the alarm.
Attackers work in minutes; organizations respond in days. In that gap, any isolation step that depends on someone reading logs and pulling a network cable by hand may come too late. If internal detection can’t act and block on its own, by the time IT notices, ransomware may already have reached core databases, file servers and backup systems, causing serious damage to the business.
Why isn’t EDR enough? How EDR and NDR divide internal network defense
Many organizations assume that EDR on every computer plus a firewall adds up to a secure internal network. But the firewall only watches traffic in and out of the network, and antivirus or EDR only watches individual devices. Between them lies a large blind spot: lateral movement inside the network.
- The limits of EDR: EDR needs an agent installed on each endpoint and server to monitor behavior. It works well on devices that can run that software, but printers, IP cameras, OT controllers on the production line and third-party NAS can’t run an EDR agent. EDR also observes behavior inside a single device, and seen from any one host, lateral movement often looks like an ordinary connection. Once attackers gain administrator rights, they can simply disable the agent.
- Why NDR (network detection and response) offers broader, proactive defense: NDR works at the network layer, analyzing traffic between devices at the switch. With nothing to install device by device, every device connected to the network falls within its view, and it focuses on abnormal connections from one device to another.
EDR protects the endpoints themselves; NDR protects the paths between them. The two work hand in hand.
QNAP ADRA NDR X: turn your NAS into the brain of internal network defense that automatically detects, traps and isolates lateral threats
To lower the budget and skills barriers that small and mid-sized businesses face, QNAP offers ADRA NDR X, a dedicated network detection and response solution. It’s a free download from App Center with no per-device license fees. Once installed, your QNAP NAS becomes the NDR analysis hub for your internal network. Pair it with a compatible switch to get started, with no changes to your existing network architecture. Key capabilities include:
- Catches new attacks, too: On top of more than 43,000 attack signatures, ADRA NDR X uses machine learning to learn each device’s normal activity and flags behavior that deviates from it.
- Spots attackers before they move: ADRA NDR X sets decoys (honeypots) across the internal network to lure hidden malware into the open, so you can defend proactively instead of waiting for an alert.
- Keeps the damage contained: Based on your policies, it automatically cuts off an infected device’s network connection while every other device keeps running, and NAS snapshots preserve a recoverable version of your files.
- Clear answers without a security expert: Built-in AI instantly summarizes each threat and recommends a response, so IT knows what to do next and the business has an overall risk report to review and act on.
*Note: Higher-end NAS models are recommended for AI features.
Internal network health check: three questions that reveal your detection gaps
IT and security leaders can start by checking three things:
- Visibility into blind spots: Are printers, IP cameras, IoT and other devices that can’t run antivirus being monitored today? Would you know if one of them were infected?
- Automated blocking: If a computer on your network suddenly starts mass-accessing SMB shared folders, will the system alert on it and block it automatically, or is no automated process in place yet?
- Response time: How long does it currently take your organization to go from spotting an anomaly to isolating the infected device?

The report scores 1,838 organizations’ self-assessments across eleven controls spanning four stages: data protection and backup, identity and access control, threat monitoring and active defense, and business continuity and recovery. Results are cross-analyzed by region, industry and company size, so you can benchmark directly against peers. The report also sets out priority improvements for each maturity tier as a starting point for planning your next step.
Frequently asked questions (FAQ)
-
Is QNAP ADRA NDR X really free? Will we pay more in license fees as we add devices?
The ADRA NDR X software is completely free, with no per-device license fees at all. Most security vendors charge annual NDR fees based on the number of monitored IPs or traffic volume, so the more devices you have, the more you pay. QNAP makes it a free install straight from the QTS / QuTS hero App Center. As long as you have a supported QNAP NAS and a compatible switch, you won’t pay license fees whether your network has 50 devices or 500. -
We already have a firewall and antivirus. Why do we still need NDR inside the network?
Because the firewall only watches traffic entering and leaving the network, and antivirus or EDR only watches individual devices. Between them lies a large blind spot: lateral movement inside the network. Attackers rarely break through firewalls head-on these days; they usually slip in through phishing emails or an employee’s laptop. Once inside, they hop between printers, NAS and colleagues’ computers over SMB file shares, and the firewall sees none of it. Only NDR, which monitors device traffic at the switch layer, can catch this kind of spread. -
Our network printers and IP cameras can’t run antivirus. What if attackers use them as a stepping stone?
That is exactly why you need NDR: it’s agentless, so nothing has to be installed on the device. Printers, cameras, production machines and contractors’ laptops may not be able to run EDR, but any device that connects to the network has to go through the switch. NDR (such as QNAP’s NDR solution) monitors connection traffic directly at the switch, so if a printer suddenly starts making abnormal connections to other computers or scanning the network, it can be knocked offline at the network layer. -
Will copying switch traffic to the NAS for security analysis slow down our network?
No. It won’t slow anything down or affect existing network traffic. ADRA NDR X works through port mirroring: the switch simply sends a copy of the packets to the NAS for inspection, rather than placing the NAS on the main data path. Even if the NAS reboots or runs at full load, office network traffic carries on as normal. The switch only cuts off an infected computer’s port when ransomware is detected. -
We only have part-time IT and no dedicated security team. Will we understand NDR’s complex alerts?
Yes. The biggest headache with traditional security tools is the thousands of log entries they generate every day that nobody has time to read. ADRA NDR X’s built-in AI analysis translates complex attack data into plain-language threat summaries and recommended next steps. Even more important, its automatic isolation blocks the connection the moment ransomware is detected, with no need to wait for IT to read logs and pull cables by hand.
