Phishing attacks are evolving at an alarming rate, driven by generative AI that enables cybercriminals to create highly convincing and personalized campaigns. As traditional reputation-
based defenses struggle to keep pace, advanced AI-powered anti-phishing solutions are becoming essential. In this blog, we will explore BUFFERZONE’s NoCloud® AI anti-phishing
solution and compare it with the anti-phishing capabilities of Microsoft Edge [2] and Google Chrome [1]. We will examine how BUFFERZONE leverages its innovative NoCloud® AI
technology to execute AI at the endpoint, providing superior protection, privacy, and performance. This approach has allowed BUFFERZONE to achieve a 21.62% improvement in
detection rates over Chrome and a 25% improvement over Edge when validating new phishing attacks¹.

The Growing Threat of Phishing

Phishing continues to be a leading cybersecurity threat, with more than 80% of organizations worldwide reporting such attacks. The emergence of generative AI has made it easier for
attackers to create sophisticated phishing websites and emails with minimal effort. Traditional solutions that depend on URL reputation lists or cloud-based analysis are becoming less
effective due to the short lifespan of phishing sites and the privacy concerns related to data transmission. This situation highlights the need for advanced endpoint-based solutions, such
as BUFFERZONE® NoCloud® AI.

BUFFERZONE NoCloud® Anti-Phishing Solution

BUFFERZONE® anti-phishing solution, integrated into its Safe Workspace® platform, is a lightweight browser extension available for Chrome and Edge. Unlike conventional approaches,
it harnesses the power of the new AI PC Neural Processing Unit (NPU)/ GPU and CPU to perform AI inference directly on the endpoint. NoCloud® technology ensures real-time phishing detection without relying on cloud infrastructure, offering significant advantages in privacy, speed, and accuracy compared to Chrome [1] and Edge [2].

Key Features of BUFFERZONE

• Real-Time Detection: Analyzes web pages using deep-learning AI models to identify phishing attempts as they occur.
• 100% Privacy: Processes all data locally on the device, ensuring sensitive information never leaves the endpoint.
• Performance Optimization: Leverages NPU and integrated GPU for over 40% faster inference compared to CPU-based processing and 70% lower detection latency than cloud-
  based solutions.
• Zero-Trust Integration: Builds on BUFFERZONE® Safe Workspace® platform, which uses application isolation and content disarming to prevent threats from reaching endpoints.

Capabilities Comparison

Analysis

• Superior Detection Accuracy for Phishing Threats

BUFFERZONE® NoCloud® delivers a significant leap in phishing detection accuracy, achieving a 21.62% improvement over Google Chrome and a 25% gain over Microsoft
Edge when identifying novel phishing attacks. This advancement empowers security teams to proactively defend against zero-day threats, reducing organizational exposure
and incident response costs.

• Unmatched Endpoint Privacy and Compliance

BUFFERZONE® on-device processing ensures no sensitive data leaves the endpoint, making it ideal for organizations with strict compliance requirements. In contrast, both
Edge and Chrome rely on cloud-based analysis, which may expose user data to privacy risks.

•  Optimized NPU Inference
  By harnessing the capabilities of hardware acceleration Neural Processing Unit (NPU), BUFFERZONE® delivers up to 40% faster inference compared to traditional CPU-
  based processing. It also reduces latency by up to 70% versus cloud-dependent solutions, ensuring real-time threat prevention without degrading the user experience.
  While Chrome
  and Edge offer cloud agility, they inherently introduce latency and potential bottlenecks due to external data roundtrips.

How BUFFERZONE Leverages NoCloud® AI for Next-Generation Phishing Protection

BUFFERZONE® NoCloud® AI technology represents a fundamental shift in the architecture of anti-phishing solutions by moving AI inference from the cloud to the endpoint.
This decentralized approach enhances both security and privacy while enabling real-time threat detection.  Here is how it works:

1. On-Device AI Inference: NoCloud® runs deep-learning models on the device’s NPU, GPU, or CPU. The NPU, optimized for AI workloads.
2. Privacy-First
   Unlike traditional cloud-based security tools, NoCloud® processes all data locally.  Sensitive user information, including browser history and form inputs, remains on the device,
   ensuring full control over data privacy. This privacy-first design helps organizations meet strict compliance standards such as GDPR, HIPAA, and CCPA without sacrificing protection.
3. Real-Time, Multi-Layered Threat Detection
   NoCloud® employs a suite of specialized AI engines to analyze web activity in real-time without compromising only on known previously detected threats based on reputation.
4. Seamless Zero-Trust Security Integration
   As a core component of BUFFERZONE’s Safe Workspace® solution, NoCloud® operates within a zero-trust framework.  Application isolation and content disarming further harden
   the endpoint, ensuring that even if threats are encountered, they are neutralized before reaching critical systems.

Leading the shift toward endpoint-centric cybersecurity, BUFFERZONE® is at the forefront of the edge computing movement in cybersecurity, where threat detection occurs closest to
the data source.  By leveraging hardware CPU acceleration, BUFFERZONE® is setting a new benchmark for AI-powered, endpoint-driven security solutions -delivering unmatched speed, accuracy, and data sovereignty

Conclusion

As phishing attacks become increasingly sophisticated, BUFFERZONE’s NoCloud® AI stands at the forefront of cybersecurity innovation. By executing advanced AI models directly on
the endpoint, BUFFERZONE® offers a distinct advantage over cloud AI dependent solutions like Google Chrome and reputation-based systems such as Microsoft Edge.  This architecture
delivers superior detection accuracy, uncompromising privacy, and high-performance threat response.

Beyond anti-phishing, BUFFERZONE’s Safe Workspace® extends protection through robust isolation of browsers, external media, email attachments, and embedded links – ensuring
threats are contained before they can compromise your environment.  To learn how BUFFERZONE® can elevate your organization’s cyber defense posture, visit bufferzonesecurity.com.
