- CAPTCHA Challenge Response A CAPTCHA challenge response is the answer a user submits to prove they're human — the paired half of a CAPTCHA's challenge-response verification.
- Captcha Solver A service or model that completes CAPTCHA challenges on behalf of automation, so a bot can pass a check it was never meant to pass.
- Click Fraud The deliberate manipulation of digital advertising metrics through automated scripts or human labor that generate fake clicks, impressions, or engagements to deplete ad budgets or inflate revenue.
- Cost Transparency The principle of clearly disclosing all costs and pricing information to users without hidden fees.
- Crawler A program or automated script that systematically browses the web to index, collect, or analyze data from websites.
- Credential Stuffing An attack where bots try stolen username/password pairs from one breach across multiple websites.
- Cybercrime Criminal activities carried out using computers, networks, or digital technologies to commit fraud, theft, or cause harm.
- Cybersecurity The practice of protecting systems, networks, and programs from digital attacks, ensuring confidentiality, integrity, and availability of information.
D
- Data Minimization A privacy principle that advocates collecting, processing, and storing only the minimum amount of personal data necessary to fulfill a specific purpose.
- Data Poisoning The deliberate injection of malicious or incorrect data into training datasets to manipulate machine learning models.
- Data Protection The safeguarding of personal and sensitive information from unauthorized access, loss, or misuse.
- DDoS (Distributed Denial of Service) A cyber attack that floods a network, server, or website with excessive traffic to overwhelm it and deny service to legitimate users.
- Decentralized Architecture A system design approach that distributes data and processing across multiple nodes or locations, enhancing security, privacy, and resilience.
- Device Fingerprinting A technique that collects information about a device's hardware and software characteristics to create a unique identifier.
- DNS The Domain Name System translates human-readable domain names into IP addresses used by computers to identify each other on the network.
- Dynamic CAPTCHA A CAPTCHA system that adapts its challenges based on user behavior and context, enhancing security and user experience.
F
- Firewall A network security system that monitors and controls incoming and outgoing traffic based on predetermined security rules.
- Fraud Detection: Methods, Tools & How to Stop Bot-Driven Fraud The process of identifying deceptive or illegal activities, particularly in digital environments where automated systems attempt to exploit services.
M
- Machine Learning A branch of artificial intelligence that enables computers to learn and make decisions from data without explicit programming.
- Malware Malicious software designed to harm, exploit, or gain unauthorized access to computer systems and networks.
- Man-in-the-Middle Attack A cyberattack where an attacker secretly intercepts and potentially alters communications between two parties who believe they are directly communicating with each other.
- Multi-Factor Authentication A security method requiring users to provide two or more verification factors to gain access to accounts or systems.
P
- Personally Identifiable Information Any data that can be used to identify an individual, either directly or indirectly.
- Phishing A cyberattack that uses deceptive emails, messages, or websites to trick users into revealing sensitive information or installing malware.
- Privacy The right to control personal information and online activities without unwanted surveillance or data collection.
- Privacy-First Architecture A system design approach that prioritizes user privacy by integrating data protection principles into the core technical foundation of products and services.
- Procaptcha A privacy-first CAPTCHA solution that uses advanced machine learning techniques to provide secure and user-friendly verification.
- Proof of Work A computational puzzle that a client must solve before being granted access — invisibly raising the cost of automation without inconveniencing real users.
- Proxy — Types, Uses & How Bots Exploit Them An intermediary server or service that forwards requests between clients and other servers, often used for privacy, security, or caching.
R
- Ransomware Malicious software that encrypts victims' files or locks their systems, demanding payment for restoration of access.
- Rate Limiting A technique that controls the number of requests a user or system can make within a specified time period.
- reCAPTCHA A Google service that uses advanced risk analysis techniques to differentiate between human users and bots, often through interactive challenges.
- Residential Proxy A proxy that routes internet traffic through real residential IP addresses, making requests appear as if they originate from actual homes.
- Risk Score A numerical value assigned to a user or entity based on their behavior and interactions, used to assess the likelihood of malicious activity.
S
- Security The protection of systems, networks, and data from unauthorized access, attacks, and damage.
- SIMD (Single Instruction, Multiple Data) A class of CPU instruction that applies one operation to several pieces of data at once. How long these instructions take to run is a property of the physical processor, so they are useful for bot detection.
T
- Threat Detection: How Real-Time Monitoring Stops Cyberattacks The process of identifying potential security threats, attacks, and anomalous activities across systems, networks, and applications.
- Threat Protection: Strategies to Prevent & Respond to Cyber Threats Security measures and technologies designed to defend against cyber threats, including malware, attacks, and unauthorized access attempts.
