6 Best Mobile App Security Companies in 2024

Every time you order food, check social media, or access your bank account via your smartphone, you’re engaging with a mobile app. Mobile apps are the backbone of our modern digital experiences, from healthcare to finance.

As your reliance on these apps deepens, so do the threats. Now, mobile application security isn’t a luxury; it’s a necessity.

Mobile application security is the combination of techniques and methods used to safeguard mobile apps from security threats and vulnerabilities. For example, messaging apps like WhatsApp use end-to-end encryption, where only the sender and recipient can read the messages, preventing eavesdropping by third parties.

Mobile app security companies identify vulnerabilities, conduct testing, and implement robust security protocols for user and data safety. 

According to Gartner, application security has the largest worldwide growth rate at 24.7% and estimated spending at $7,503 million. It’s a steady increase of 4% over the last three years.

The rising investment in application security signifies a proactive approach by businesses to strengthen their defenses in the face of growing cyber threats.

3 Key Principles of Mobile App Security 

1. Confidentiality:

Mobile app security keeps your private information safe. For instance, in banking apps, your account details are encrypted. This means, that even if someone tries to access your data, it appears as jumbled code, ensuring your privacy and stopping unauthorized access.

2. Integrity:

Apps need to keep information correct and safe from changes. For example, healthcare apps use digital signatures to confirm patient records are genuine. 

3. Availability:

Mobile apps need to keep working, even during cyberattacks. Gaming apps use DDoS protection as an example. By having strong defenses, these apps stay available to users even during big cyberattacks.
