5 App Security Trends in 2025

When science fiction writer William Gibson wrote his debut novel Neuromancer in 1984, the dark world of cyber hackers was mostly science fiction. "Cyberspace," he wrote, is "a consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts."

There is a romantic, counterculture feel to think of interlopers who daily attempt to interfere with the legitimate affairs of the internet. But the digital dance between application creator and cyber-bad guy has reached a fever pitch in today's world. 

As we approach 2025, the world of app security continues to evolve. The changes we'll see are driven in part by technology advancements, like AI, and by new threats that are emerging. Here are five trends we're likely to see more of in the coming months. 

1. Increasing Importance of AI in Security 

Artificial intelligence is becoming standard across the tech world, especially in cybersecurity. AI-driven tools can analyze massive amounts of data to detect anomalies and possible threats in real-time. And because they're machines, they can work 24/7, improving the speed and accuracy of threat detection. 

On the other hand, companies won't be the only ones to have the power of AI at their fingertips. Hackers who get their hands on AI and machine learning can do even more damage than they are already doing. The potential power of one person to target and destroy online data or infrastructure is increasing.

2. DevSecOps Will Become More Important 

As more software is released to the cloud through virtual devices and microservices, security may become a problem. Traffic that may be hijacked, blocked, or otherwise interrupted can now be easily rerouted or reallocated to other network resources without skipping a beat. But tampering with the application itself in the processing of data — that's where the danger lies.

Developers must learn to think like hackers. For instance, it might be a good idea to hire white hat hackers to test their applications to ensure that they are ready for public release.

Integrating security practices into the DevOps process, known as DevSecOps, is becoming more prevalent. This approach involves incorporating security measures early in the software development lifecycle, enabling the identification and mitigation of vulnerabilities before deployment. This proactive strategy enhances security and reduces the time and cost associated with addressing security issues post-deployment. 

3. Increased Focus on API Security

Application Programming Interfaces (APIs) are essential for businesses to share data, power mobile apps, and integrate third-party services. However, these valuable data pipelines are also highly vulnerable to exploitation. Attackers increasingly target APIs as they offer a direct route to sensitive data and core business processes, making robust API security critical.

Unsecured or poorly designed APIs can serve as easy entry points for attackers, leading to severe consequences like data breaches, unauthorized access, and even denial of service (DoS) attacks. A well-known example is the 2019 Facebook API data leak, which exposed millions of user records due to inadequate security controls. Such incidents underline the necessity for businesses to establish stringent API security practices.

Safeguarding sensitive data will require continuous updates and monitoring, with practices such as encrypting data in transit, implementing rate limiting, and logging API activity to track suspicious access patterns. In 2025, expect a rise in dedicated API security solutions as companies recognize APIs as essential—yet vulnerable—digital connectors that require proactive defense measures.

4. Growing Importance of Zero-Trust Architecture 

Zero Trust operates on a simple yet powerful premise: "Never trust, always verify." This approach moves away from assuming that everything inside a network is secure. Instead, it requires constant verification of every user, device, and application, regardless of location or access history.

In a zero-trust model, no user or device is inherently trusted, even if it resides within the network. Every access attempt is validated through multiple layers of checks, such as multi-factor authentication (MFA), endpoint security verifications, and strict access control policies. This model significantly reduces the risk of unauthorized access and limits the potential spread of malware or breaches within a network by preventing lateral movement.

As our world becomes more reliant on remote work, cloud computing, and IoT devices, the traditional network perimeter has become almost nonexistent. This change has left companies vulnerable to sophisticated cyberattacks, as conventional firewalls and VPNs are no longer enough to secure access points. Zero-Trust mitigates these vulnerabilities by treating each interaction as potentially suspect, ensuring that each access attempt is verified and tracked in real time.

5. Prep for Quantum Computing Threats 

Quantum computing promises breakthroughs across industries, but it also threatens current cybersecurity protocols. Quantum’s power could soon render traditional encryption—like RSA and ECC—obsolete, exposing sensitive data. Cybercriminals may already be using a “harvest-now, decrypt-later” tactic, capturing encrypted data to unlock once quantum advances.

The National Institute of Standards and Technology (NIST) released quantum-safe encryption standards in August, providing critical guidelines for safeguarding data in a quantum-enabled future.  

Preparing for this shift means assessing which data needs protection for the next 5-20 years, beginning upgrades to quantum-safe encryption, and staying agile as the technology evolves. With proactive measures, organizations can shield sensitive information from the imminent rise of quantum threats.

Final Thoughts: Everyone Needs to Play Defense

We'll never be able to protect ourselves against all the possible digital threats, but we should never let down our guard. We need to stay at least one step ahead if we want to survive. It's a shame it has to be that way. But accepting online realities means we see the need to be as prepared as possible to address them. Protecting applications is now a priority.
