As technology and risk evolve, they bring new terms and acronyms into our lives just as fast. It can be challenging to stay up-to-date, yet it is essential to stay informed. Here is a list of some of the key cybersecurity abbreviations industry professionals need to lock into their lexicon in 2026.
Being fluent in these security definitions will enable security leaders to stay informed about industry changes, understand their implications, and recognize their significance.
- BYOK: Bring Your Own Key | BYOK is a security model that allows organizations to generate and manage their own encryption keys while using third-party cloud services, ensuring greater control over data protection and regulatory compliance.
- CCKM: CipherTrust Control Key Management | CCKM by Thales enables organizations to maintain ownership and control of encryption keys used in cloud services, supporting customer-managed keys and external key management for regulatory compliance and data sovereignty.
- CIAM: Customer Identity and Access Management | CIAM focuses on managing and securing customer identities at scale, enabling secure authentication, consent management, and seamless digital experiences while protecting personal data and privacy.
- DLP: Data Loss Prevention | DLP is a combination of security practices, processes, and tools that control and enforce mechanisms to prevent sensitive information from leaving the organization’s control via unauthorized means.
- DPoD: Data Protection on Demand | DPoD is a cloud-delivered service model by Thales that provides on-demand encryption, key management, and access control, allowing organizations to protect sensitive data without managing underlying infrastructure.
- DSP: Data Security Platform | A data security platform is an umbrella platform of tools that simplify the discovery, protection, and management of sensitive data within modern environments.
- DSPM: Data Security Posture Management | DSPM is a data-first solution that discovers, classifies, and identifies data risk across cloud, on-premises, and hybrid environments.
- EKM: External Key Management | EKM refers to the use of externally managed encryption keys—often stored in on-premises or customer-controlled HSMs—to secure data in cloud services, enabling centralized key governance and separation of data and key control.
- FAM: File Activity Monitoring | FAM is a data security capability that monitors, analyzes, and alerts on file access and usage activity across on-premises and cloud environments, helping organizations detect insider threats, compromised accounts, and anomalous behavior involving sensitive files in structured and unstructured data.
- FIDO: Fast IDentity Online | FIDO is a collection of authentication protocols that enable users to sign in to apps and websites using phishing-resistant cryptographic passkeys.
- FIPS: Federal Information Processing Standards | FIPS are U.S. government standards that define security and cryptographic requirements for systems protecting sensitive information, commonly used as a benchmark for trusted encryption, key management, and hardware security modules.
- HSM: Hardware Security Module | HSMs are physical hardware devices that serve as the root of trust, safeguarding, generating, and managing cryptographic keys for increased authentication security.
- HYOK: Hold Your Own Key | HYOK is an advanced key-ownership model in which encryption keys are generated, stored, and controlled entirely outside the cloud provider’s environment, preventing the provider from accessing protected data and supporting strict data sovereignty requirements.
- IAM: Identity and Access Management | IAM is a security framework that ensures the right people have access to the right resources at the right times across cloud, on-prem, and hybrid environments.
- MFA: Multi-Factor Authentication | MFA is a secure authentication method that combines credentials with additional factors, such as tokens and biometrics, to enhance the integrity of logins.
- OTP: One-Time Password | OTP is an authentication mechanism that uses a single-use, time-bound password—often delivered via hardware token, mobile app, or SMS—to reduce the risk of credential replay and unauthorized access.
- PAM: Privileged Access Management | PAM is an identity security tool that manages the way human and non-human identities with elevated access interact with critical systems and data.
- PKI: Public Key Infrastructure | PKI is a cryptographic framework that uses digital certificates and public-private key pairs to enable secure communication, authentication, and data integrity across users, devices, applications, and machines.
- PQC: Post-Quantum Cryptography | PQC focuses on quantum-resistant cryptographic algorithms to mitigate the risks introduced to current encryption schemes by quantum computers.
- QKD: Quantum Key Distribution | QKD is an emerging cryptographic technique that uses the principles of quantum mechanics to securely exchange encryption keys, offering future-facing protection against threats posed by quantum computing.
- SSO: Single Sign-On | Single Sign-On is an authentication process that allows users to authenticate once and gain access to multiple cloud and enterprise applications.
- STA: SafeNet Trusted Access | STA is a cloud-based access management service offered by Thales that enables secure authentication, adaptive access control, and centralized policy enforcement for workforce, partners, and customers across cloud and hybrid environments.
- ZTNA: Zero Trust Network Access | ZTNA is a security framework that replaces implicit network trust with identity-centric, context-aware access controls, granting users and devices access only to the specific applications and resources they are authorized to use.
As the industry evolves, this list will only grow and evolve with it. Security changemakers carry incredible weight as we head into 2026, as our roles increasingly intertwine with transformational business priorities. These are exciting times that require us to stay on the cutting edge of technology, risks, and, yes—even acronyms.
