Welcome to 2025—84 years since the invention of the first computer and 56 years since the foundations of today’s Internet were laid. Technology continues to evolve at a breathtaking pace, with advancements in Artificial Intelligence, Quantum Computing, and digital currencies reshaping our world. Alongside these innovations, cybersecurity is undergoing rapid transformation to address new challenges and opportunities.
In this blog post, we’ll explore five emerging cybersecurity trends and topics poised to gain momentum in 2025.
1. Confidential Computing Will Become Essential for Securing Data in AI and LLM Models
As companies increasingly migrate their data to the cloud, they’ve implemented protective measures like encryption and access management to achieve a well-defined, secure environment. Now organizations are also shifting their AI workloads to the cloud, where the significant cost of AI hardware makes cloud processing the only feasible option for many, as on-premises installations can be prohibitively expensive. This shift brings new challenges around protecting privacy, security, and intellectual property in cloud-based AI environments to safeguard the AI models themselves—and the data input and output from them.
Given these developments, there will be a significant boost in confidential computing adoption, driven by the growth of AI processing in the cloud.
2. Post Quantum Cryptography Will be the New Standard for Emerging Applications
Another cybersecurity trend for 2025 is the shift to post-quantum cryptography (PQC), as enterprises race to stay ahead of this emerging threat.
As quantum computing is poised to revolutionize data security, it will soon render traditional cryptographic methods obsolete. The urgency for enterprises to transition to quantum-safe cryptographic algorithms cannot be overstated. Asymmetric cryptography, the backbone of many current security systems, will become increasingly vulnerable as we approach the end of this decade—making the shift to quantum-safe alternatives imperative for CISOs, IT security professionals, and data privacy experts.
With the first final standards for Post Quantum Cryptography being published by NIST in August 2024, companies will become more confident to implement these algorithms in their applications. Most likely, many implementations will still use hybrid methods (combination of classic + PQC cryptography) before switching solely to PQC.
3. There will be an increase in regulations for AI, digital currencies, and software supply chains
Compliance demands will continue to grow, with future regulations likely to include requirements for AI, post-quantum cryptography, software supply chain security, and safeguarding digital currency. Organizations will need solutions to stay agile and secure in this landscape, with tools for data protection, key management, and secure payments—helping them maintain compliance in a dynamic regulatory future.
Examples: In 2025, the European Union will strictly enforce key directives like NIS2, DORA, and CRA to enhance cybersecurity and resilience across its member states. Additionally, the EU AI Act positions the region as an early adopter in regulating AI, setting a precedent expected to influence countries such as Canada, Australia, Brazil, and Singapore to follow suit.
4. There will be a need for more social responsibility of cyber-awareness
In 2025, one of the emerging trends is the growing focus on the social responsibility of cybersecurity.
Cybersecurity isn't limited to mitigating or preventing the financial losses caused by cyberattacks, fraud or data manipulation. More often than not, cybercrime or the lack of cyber awareness has very personal consequences: people traumatized by identity theft, perpetuation of disinformation, and loss of trust in institutions based on lack of transparency and accountability. Companies and authorities will need to be more aware of their responsibility for the social impact of what they do in a world where data ownership can change or save lives.
Recommendation: Implementing preventive measures, including comprehensive cybersecurity staff training programs, to strengthen organizational defenses. Additionally, fostering an open and transparent corporate culture can encourage proactive communication and collaboration, further enhancing your organization’s resilience against cyber threats.
5. There will be an increased need for crypto agility
In a constantly shifting threat landscape, crypto agility—the ability to adapt encryption standards, key sizes, and algorithms—is becoming essential. The cloud, where workloads are increasingly moving towards, lacks the inherent protections of traditional on-premises data centers, making encryption, authentication, authorization, and data integrity critical to secure distributed data storage and processing. Organizations that have invested in crypto agility will have a distinct advantage as security requirements evolve. This will also be especially important as the advent of quantum threats emerges in the coming years, rendering traditional defenses useless.
Recommendation: With the rapid emergence of new breakthroughs in technology, cryptography and cybersecurity must not only keep up but stay several steps ahead. Crypto agility is a fundamental requirement to achieve this. When selecting new cybersecurity tools, devices, or applications, prioritizing crypto agility as a key feature is essential.
