Anti-Phishing Service – GenAI URL Inspection

Spambrella relies on advanced AI technology from Proofpoint to help protect your organization from threats that are distributed via email, including phishing and targeted attack–emails sent to your org/business community to trick people into giving up their network credentials. These messages and the websites they link to often look legitimate, even to the discerning eye, because they may use your own logos and valid email addresses and other contact information.

Spambrella URL Defense protects users and organizations network resources by blocking access to malicious websites. Links in all email messages are evaluated using a variety of sophisticated techniques to determine the likelihood that they lead back to phishing or malware websites.

If links can’t be definitively classified as safe when the message is received, the URL is rewritten so that clicking it will cause URL Defense to evaluate the linked website a second time. If the link is safe, you will see no difference.

Protection from Phishing and Domain Spoofing

Phishing is a term used to describe various scams that use (primarily) fraudulent e-mail messages, sent by cyber criminals, to trick you into divulging personal information. The criminals use this information to steal your identity, rob your bank account, or take over your computer. Counterfeit web sites, using “hijacked” company brands and logos, are created to lure you into revealing information you would not want to be public knowledge. These digital thugs are “phishing” for any data they can obtain to prey on people and further their criminal activities.

Even the most experienced internet user can be duped into entering information based on a targeted phishing email. Often phishing emails are sent to a small number of users in order to avoid detection. This is why protection at click-time is so important in today’s ’email to web’ communication world.

The anti-phishing solution for your business

Spambrella’s anti-phishing service is now one of the most sought after service features in the cloud security marketplace. Spambrella by default runs user scan-time and click-time protection for emails that are scanned for URL reputation and IP threat. When the email is filtered, and again when the user clicks a link. This unique feature protects users from any changes in URL reputation.

User responsibility and awareness can only take your business users so far

There are many tools and service subscriptions available for anti-phishing education in today’s world, all of which disturb the day-to-day mechanics of your workforce. Common sense will go a long way to protecting your systems. However, recent surveys carried out by Proofpoint show that only a very small percentage of individuals can detect a phishing attempt. Even seasoned professionals are susceptible to making wrongful judgments.

URL Defense Functions

URL Defense has two functions, ‘scan time’ and ‘click time’. The scan time is run at the time of entry to Spambrella servers, the click time function is when the user clicks on the URL in an email. The reason the two functions are in place is that the email delivery may be hours/days before the user clicks the link.

Sophisticated (spear-phish) attacks are carried out with clean emails entering your organization with safe URLs embedded from trusted IPs/servers to bypass email security systems. Once the email is delivered, the malicious content is then added to the server/website or download link.

Our click time URL defense protects the user during this function by re-checking the destination URL/server/IP, whereas other services that claim to be leaders in Email Security do not provide this level of protection.

Spambrella AI Phishing Detection

The use of Artificial Intelligence (AI) in Spambrella email threat protection has revolutionized the way organizations defend against sophisticated email-based threats. Here are several ways AI is leveraged by Spambrella in email threat protection:

Phishing Detection:

Spambrella uses AI-powered algorithms to analyze the content, structure, and context of incoming emails to identify phishing attempts. By recognizing patterns and anomalies in email headers, body content, and sender behavior, AI models can accurately detect phishing emails, even those with sophisticated social engineering techniques.

Behavioral Analysis:

Our AI-driven email threat protection systems utilize behavioral analysis to identify unusual or suspicious email activity. By establishing baseline behavior for each user or group, AI algorithms can detect deviations from normal patterns, such as sudden spikes in email volume, unusual login locations, or atypical communication patterns, indicating potential security threats.

Anomaly Detection:

Spambrella machine learning AI models employ anomaly detection techniques to identify email-based threats that deviate from expected norms or behaviors. By analyzing metadata, content, attachments, and sender-receiver relationships, AI algorithms can detect anomalies such as unusual email signatures, unexpected file types, or suspicious domain names, signaling potential security risks.

Content Analysis:

AI-based content analysis examines the text, images, and attachments within emails to identify malicious or suspicious content. Natural Language Processing (NLP) algorithms analyze email content for indicators of phishing, malware, or social engineering tactics, enabling organizations to block or quarantine malicious emails before they reach users’ inboxes.

URL and Link Analysis:

Spambrella AI-powered email threat protection solutions analyze URLs and hyperlinks included in emails to assess their legitimacy and safety. By comparing URLs against threat intelligence feeds, reputation databases, and historical data, AI algorithms can identify malicious links leading to phishing websites, malware downloads, or other malicious destinations, preventing users from accessing harmful content.

Zero-Day Threat Detection:

AI-driven email threat protection systems can detect and mitigate zero-day threats—previously unknown or undocumented vulnerabilities or attack methods. Spambrella is continuously learning from new data and evolving threat landscapes, our AI models can adapt and identify emerging email-based threats in real-time, providing proactive protection against unknown and evolving threats.

User Behavior Analytics (UBA):

Proofpoint threat teams use AI-powered UBA tools to analyze user behavior within email systems to detect anomalies, unusual activities, or potential insider threats. By monitoring email usage patterns, access permissions, and communication behaviors, AI algorithms can identify suspicious activities, compromised accounts, or unauthorized access attempts, enabling organizations to take timely action to mitigate risks.

Automated Response and Remediation:

The Spambrella AI-driven email threat protection solutions automate response and remediation actions to mitigate security incidents in real time. By integrating with security orchestration and automation platforms via Proofpoint, Spambrella AI algorithms can trigger predefined actions such as quarantining suspicious emails, blocking malicious senders, or alerting security teams to investigate potential threats, reducing response times and minimizing the impact of security incidents.

Overall, AI plays a crucial role in enhancing the effectiveness, efficiency, and agility of email threat protection solutions, enabling organizations to defend against a wide range of email-based threats with greater accuracy and speed. Our anti-phishing technologies benefit hugely from the innovations our team and partners are taking with the fast-moving AI developments.
