Click-jacking is a type of cyberattack where malicious code is embedded in a website to deceive a user into clicking a button, link, or other element that results in unintended actions or functions being performed. Click-jacking can force users to unknowingly download malware, divulge account credentials, and more.

Clone phishing

Clone phishing uses a duplicate or “clone” copy of an email from a trusted source to deceive the recipient. Instead of creating their own email, the hacker duplicates an existing email from a well-established brand to lure their victims. The email is typically either one the recipient has received in the past or at least isn’t surprised to be receiving. The legitimacy of the cloned email tricks recipients into clicking on malicious links or giving up sensitive information.

Cloud access security broker (CASB)

A cloud access security broker, or CASB, protects companies using cloud-hosted services and applications. CASBs act as a firewall between enterprise users and their cloud applications—managing and protecting the data being accessed and stored there. Cloud access security brokers can either be on-premise or cloud-based and fill any gaps in security to allow a company’s security policy to extend beyond their own infrastructure to cloud-based applications.

Cloud email

Cloud email—such as Gmail—is email hosted by a cloud-based email service provider. It’s an alternative solution for organizations that don’t want to host email services on their own infrastructure. Since cloud email is stored and hosted in the cloud, its major benefit is the ability for users to access their email from anywhere—without needing to connect to a server.

Cloud email security supplement (CESS)

Cloud email security supplements, or CESSs, provide additional security measures specific to phishing-related attacks. They are typically utilized in particular use cases where organizations are regularly facing specific yet sophisticated threats that are hard to detect. CESSs are beneficial for organizations that need real-time scanning of inboxes or require enhanced detection and remediation methods for email-related cyberattacks. With the right CESSs in place, organizations can benefit from an additional layer of security that specifically addresses threats that are prevalent to their business.

Cloud security

Cloud security, also referred to as cloud computing security, is the discipline of protecting cloud-based systems from cyberthreats, including their data, infrastructure, and applications. Cloud security encompasses a collection of technology solutions, processes, and controls used by cloud service providers to defend against internal and external threats. With the growing popularity of cloud services and applications, cloud security, particularly for enterprises, has increased in importance.

Computer vision

Computer Vision is a field of computer science that uses Artificial Intelligence (AI) to understand visual data (imagery). If AI is used to “think” by analyzing and interpreting data inputs, Computer Vision is used to “see” by analyzing and interpreting visual inputs.

Content disarm and reconstruction (CDR)

Content disarm and reconstruction (CDR) is a form of web content filtering which scans downloaded files for threats before they reach the endpoint device. The process removes any potentially malicious elements from the file while still preserving its original functionality.

Cousin domain

A cousin domain—also referred to as a lookalike domain—is a domain that deceptively resembles the name of another website. Cousin domains use common typos ( or numbers ( in an effort to trick fast-moving Internet users into thinking they’re on a legitimate website. Once users land on the cousin domain, the hackers begin carrying out phishing attacks on the user.
