Backup (backup copy)
Automatic backup of the company's files, systems, and applications, stored off-site. This allows you to restore data and resume operations quickly, even if a computer or server breaks down, is stolen, or becomes inoperable.
Immutable backup
A backup that cannot be modified or deleted during the defined retention period. It is one of the most effective defenses against ransomware because it ensures that there is always an intact version of the data available for recovery.
Disaster Recovery
The ability to restore critical systems to operation after a serious incident—such as a cyberattack, hardware failure, fire, or flood. The systems are restored from a copy hosted in the cloud, reducing business downtime.
DLP (Data Loss Prevention)
A set of controls that prevents confidential information from leaving the company improperly. It allows, for example, blocking the copying of data to USB drives or external hard drives, defining lists of authorized devices, and remotely deleting data.
EDR (Endpoint Detection and Response)
Unlike traditional antivirus software, which only recognizes known threats, EDR continuously monitors device behavior. If it detects suspicious activity, it blocks it immediately and allows for the quick recovery of affected data.
Endpoint
Any device that connects to the company's network and through which information flows—computers, laptops, servers, or NAS devices—is the most common target of attacks, so these are also the first things to protect.
Vulnerability and Update Management
Continuous monitoring of systems and applications to identify security vulnerabilities before they are exploited, followed by the automatic application of patches that fix them. It is one of the simplest and most effective ways to reduce risk.
Malware
A general term for malicious software designed to damage systems, steal information, or take control of devices. It includes viruses, Trojans, spyware, and ransomware.
Phishing
An attempted scam in which the attacker impersonates a trusted entity—such as a bank, a supplier, or even a colleague—to obtain credentials, banking information, or access to systems. It typically arrives via email, text , or instant message.
Ransomware
An attack that encrypts a company's files and demands a ransom payment to unlock them. Effective protection is based on three layers: preventing access, detecting anomalous encryption in real time, and recovering data from secure backups.
Restoration (restore)
The process of restoring data from a backup. It can be a full restore (the entire system) or a granular restore (just a file, a folder, or a mailbox), depending on what needs to be recovered.
XDR (Extended Detection and Response)
An evolution of EDR that extends detection and response beyond devices to also cover applications, email, and data. It provides an integrated view of what’s happening across the entire organization and accelerates incident response.
