Multi-Scanning Antivirus: Boost Your Threat Hunting With Multiple Layers

Multi-scanning anti-virus, also known simply as multi-scanning, uses multiple anti-malware or antivirus engines concurrently to scan for threats. This approach enhances malware detection and improves overall cybersecurity.

Here are three reasons you should consider multi-scanning, key considerations for your security team when implementing such an approach — and how ReversingLabs’s multi-scanning delivers best-of-class performance.

Improved Detection Rates

The primary advantage of multi-scanning is its ability to increase malware detection rates significantly:

• No single antivirus engine is 100% effective against every malware threat.
• Different engines use scanning methodologies and update their malware definition files at different frequencies.
• Combining multiple engines increases the likelihood of detecting new and unknown threats substantially.

For example, while a single antivirus engine might have a detection rate of around 98%, combining multiple engines can push this rate much higher, potentially reducing the risk of infection to near-zero levels.

Faster Response to New Threats

Multi-scanning can more efficiently identify malware outbreaks by consolidating virus definition database updates from multiple sources. This approach reduces the time of exposure to new malware, potentially bringing it down to less than 10 minutes when using more than 20 anti-malware engines.

This diverse approach is particularly effective against complex viruses, including polymorphic and zero-day threats that might evade traditional, single-engine solutions.

Considerations and Tradeoffs

While multi-scanning offers significant benefits, it's essential to consider some potential drawbacks:

• Performance Impact: Running multiple scan engines simultaneously can increase latency and require more computing resources.
• False Positives: As the number of engines increases, so does the likelihood of false positives. This can lead to unnecessary alerts and potentially disrupt workflow.
• Complexity: Managing multiple engines can be more complex than using a single solution, potentially requiring more IT resources and expertise.

In conclusion, multi-scanning anti-virus can provide a robust layer of protection against a wide range of malware threats, especially in high-risk enterprise environments processing large amounts of data. However, it's crucial to balance the improved detection rates with the potential increase in false positives and system resource usage. For many organizations, the enhanced security offered by multi-scanning outweighs these considerations, making it an increasingly popular choice in comprehensive cybersecurity strategies.

Multi-scanning is a powerful new tool in your belt

Multi-scanning anti-virus technology represents a significant advancement in cybersecurity, offering a robust defense against the ever-evolving landscape of digital threats. By leveraging multiple scanning engines and diverse analysis techniques, this approach addresses the limitations of single-engine solutions and provides a more comprehensive shield against malware.

ReversingLabs exemplifies the power of multi-scanning in practice, demonstrating how this technology can be effectively implemented to create a formidable file reputation solution. Its use of more than 40 scanning engines, combined with AI-driven analysis and a vast file intelligence database, showcases the potential of multi-scanning to significantly enhance threat detection capabilities.

While multi-scanning does come with considerations such as increased resource usage and potential false positives, its benefits often outweigh these challenges, especially in high-risk environments. As cyber threats continue to grow in sophistication, multi-scanning anti-virus solutions are likely to play an increasingly crucial role in comprehensive cybersecurity strategies.

For organizations, adopting multi-scanning technology could be a game-changing step toward achieving a more secure digital presence. As we move forward in an increasingly connected world, the layered protection offered by multi-scanning may become an essential component of our digital defense arsenal.
