The Best Ransomware Scanners

Best Ransomware Scanners

Scott Pickard June 14, 2023

Find malicious ransomware on your network quickly and securely with these ransomware scanners.

Ransomware poses an increasing threat to a vast number of businesses, but the threat that it poses can be offset by the clever incorporation of several security systems. The best approach to preventing ransomware attacks is the proactive scanning and mitigation of exploits through a dedicated Ransomware Scanner. These solutions use intelligent systems—from log reading to AI-Driven behavioral analysis, to catch malicious agents in the process of setting up a ransomware attack long before they can pose a threat to your network.


Throughout this article, you will see mention of the acronyms ‘SIEM’ and ‘XDR’—both of which pertain to a similar approach to handling security analytics and threat response. They differ slightly but fundamentally achieve the same thing through slightly different approaches. But what are SIEM and XDR?

  • Security Information and Event Management (SIEM) focuses primarily on the scanning and detection of potential threats within a network through parsing event data and direct system logs. SIEM is the classic method of scanning for malware, ransomware, and malicious activity.
  • Extended Detection and Response (XDR) goes beyond the capabilities of SIEM by adding extra functionality beyond the standard event log analysis. This typically means the inclusion of things like behavioral analysis and has a broader focus that can extend across multiple domains. XDR is the more modern approach to ransomware detection.

Here is our list of the best Ransomware Scanners:

  1. ManageEngine Log360 A vulnerability and threat detection SIEM tool called ManageEngine Log360 operates by analyzing log and event data. All of your network devices and apps' logs may be collected, analyzed, and used with the product to produce precise security reports.
  2. CrowdStrike Falcon Insight XDR A highly competent, enterprise-grade ransomware scanner, Falcon Insight XDR from CrowdStrike aims to provide thorough and consistent insight into a broad range of endpoints.
  3. Rapid7 InsightIDR An Insight Agent allows InsightIDR, a cloud-based unified SIEM, to gather data from your whole network environment. Thanks to unified data collection, security, IT, and DevOps teams can collaborate effectively to monitor and assess their network.
  4. SpinOne A 24/7, fully automated ransomware defense tool that is designed exclusively to safeguard data on Gmail, Google Drive, and shared drives.
  5. ZoneAlarm Anti-Ransomware A commercial security program that is designed to safeguard a single device rather than a whole network, by using real-time behavior analysis to spot and neutralize ransomware threats.
  6. GravityZone Business Security For small-to-medium-sized enterprises that require a top-notch solution at an affordable price, GravityZone Business Security is one of the best ransomware scanning options on the market.
  7. Exabeam By attacking the solution from two similar sides, Exabeam offers both a SIEM and an XDR solution that can both offer significant ransomware protection.
  8. Avast One Avast offers a free ransomware scanning tool that is ideal for single devices if you need a cost-effective solution for your ransomware screening and mitigation requirements.

The Best Ransomware Scanners

1. ManageEngine Log360

ManageEngine Log360

ManageEngine Log360 is a vulnerability and threat detection SIEM product that works through the analysis of log and event data. Using the product, all of your network devices and apps' logs may be gathered, analyzed, and used to create accurate security reports. Also with the help of Log360's search tool, you can quickly sift through unprocessed logs and get the information you're looking for. Boolean operators, phrases, and wildcards are all acceptable search parameters.

Key Features:

  • App/network device auditing
  • In-depth forensic analysis
  • Privileged user monitoring
  • AD change auditing
  • Real-time event correlation

With the help of the strong correlation engine in Log360, you can combine various events that are happening in your network in real-time and determine whether they pose a threat. Over twenty preconfigured rules in Log360 can be used to find well-known attack patterns. Additionally, you can design your own correlation rules using the custom rule builder. To effectively address security issues and maintain accountability during the incident resolution process, the correlation engine and incident management module work hand in hand.

Log360 employs a STIX/TAXII threat feed processor that routinely gathers information from worldwide threat feeds and keeps you informed is included in the module, along with a database of dangerous IP addresses from around the world. Additionally, when malicious sources attempt to contact your network, you are immediately alerted through customizable automation systems.

ManageEngine Log360 has a free 30-day full trial that has no restrictions, which is more than long enough to familiarize yourself with the product. The full product is also free for up to 50 GB of storage and seven days of search retention. The Basic plan costs $300 for 75GB, with expandable storage options—the Standard plan costs $600 for 100 GB, again with more storage options, but also includes log forwarding and longer storage retention.

2. CrowdStrike Falcon Insight XDR

CrowdStrike Falcon Insight XDR

Falcon Insight XDR by CrowdStrike is a highly-professional, enterprise-grade ransomware scanner that is aimed toward comprehensive and consistent insight into a wide scope of endpoints. The system is geared towards protecting from all manner of malicious attacks, not just ransomware, which makes it an excellent choice for a long-term security solution.

The system also includes a simple-to-use Incident Workbench that can break down and analyze any presented attack while containing context and threat intelligence data. The inbuilt CrowdScore system provides situational awareness of your organization's current threat level and how it is evolving over time.

The solution comes with a 15-day free trial to test the available features within your existing business environment. Falcon Insight XDR comes as part of a full Falcon product subscription, specifically as an optional extra attached to either the Falcon Enterprise or Falcon Elite product subscriptions. The Falcon Enterprise package is listed as costing $15.99 per endpoint per month but expect additional costs to add Falcon Insight XDR to that package.

Overall, this means Falcon Insight XDR is the best option for complete security insight and protection that goes beyond just Ransomware—but if ransomware protection is all you’re looking for, then cheaper alternatives exist.

3. Rapid7 InsightIDR

Rapid7 InsightIDR

Rapid7 InsightIDR is a cloud-based unified SIEM that works through an ‘Insight Agent’ to get information from your network environment as a whole. Security, IT, and DevOps teams can work together efficiently to monitor and evaluate their environments thanks to unified data collecting. Rapid7 claim that this installed agent provides more accurate insight into the inner security of your network beyond merely reading and interpreting log/event data that is typical of SIEM products.
