WhatsApp Business is convenient, but its security falls short. If you're handling sensitive data, relying on Meta’s servers means you lack full control – and that’s a major risk. Remember the 2023 data leakage where over 500 million user records were made available for sale online? Now you do.
That’s precisely why some companies, especially in finance, healthcare, and legal services, are seeking secure WhatsApp alternatives for business that prioritize full data ownership.
The good news? You have options. Rocket.Chat, Signal, and Threema offer stronger security, better encryption, and even self-hosting. This guide explores the best WhatsApp alternatives for business, plus why a custom-built platform may be the ultimate alternative to WhatsApp.
Let’s chat about it.
The security issue – key reason why companies look for WhatsApp alternatives for business
Security is one of the biggest concerns for businesses using WhatsApp for business. While the platform offers basic encryption, it does not provide full data control, making it a risky choice for companies handling sensitive information. This is why many businesses are actively looking for a WhatsApp Business alternative that prioritizes security, compliance, and data ownership – so if you do too, you’re not alone.
Let’s take a closer look at those issues.
Lack of full data ownership
Messages sent through WhatsApp pass through Meta’s servers, meaning businesses don’t have complete control over their communication data. There’s always a risk of third-party data access, whether for analytics, advertising, or other undisclosed purposes. Businesses that rely on WhatsApp for companies must trust that their data won’t be shared, but they have no way to independently verify this.
Privacy and compliance risks
WhatsApp’s connection to Meta raises concerns about compliance with strict privacy laws like GDPR, HIPAA, and CCPA. In regulated industries such as healthcare, finance, or legal services, using a messaging app that doesn’t offer full compliance and data encryption can result in legal risks and hefty fines. Companies searching for an alternative to WhatsApp for business need a platform that allows them to self-host and meet industry-specific security requirements.
Encryption limitations
While WhatsApp offers end-to-end encryption, it only applies to one-on-one and group chats – not business API messages. Metadata is still collected, including who you contact and when, which can be valuable for tracking and profiling users. Companies looking for truly WhatsApp alternatives for business need an app that encrypts not just messages but also metadata and stored communications.
Dependence on a third-party infrastructure
WhatsApp is owned and operated by Meta, meaning businesses are dependent on the tech giant’s policies, security decisions, and potential data-sharing practices. A sudden policy change could affect how businesses communicate with customers, making companies vulnerable to unpredictable restrictions. Choosing a WhatsApp Business alternative that offers self-hosting or decentralized infrastructure ensures businesses remain in control of their communications.
Other significant issues with WhatsApp for business
- High API costs make WhatsApp a less scalable option for many businesses.
- Limited integration options prevent businesses from fully automating and customizing workflows.
- Restrictions on chatbot automation and bulk messaging make WhatsApp for companies less flexible for customer engagement.
So, what are the best WhatsApp alternatives for businesses currently available on the market?

What are the key security features businesses should prioritize in WhatsApp alternatives for business in 2025
When building a WhatsApp Business alternative in 2025, businesses should focus on several key areas to ensure success and user adoption. Here’s what you need to consider in particular:
Security and privacy
- End-to-end encryption (E2EE): encrypt messages so only the sender and recipient can access them, ensuring no third party (including the app provider) can intercept or read communications.
- Open-source code: using open-source code allows external experts to audit the app for vulnerabilities, increasing transparency and accountability.
- Multi-factor authentication (MFA): implement MFA or, at the very least, two-factor authentication to secure user accounts by requiring multiple forms of verification during login.
- Self-destructing messages: include options for disappearing messages that automatically delete after a set period, leaving no trace on servers or user devices.
- Encrypted backups: provide encrypted backups for chats and media to protect data stored on cloud services from unauthorized access.
- Metadata protection: minimize the collection of metadata (e.g., sender, recipient, and timestamp information) to enhance user privacy and prevent tracking. Metadata has been at the centrestage of WhatsApp security compromise in 2024 – it was neither collected nor shared appropriately.
- Regulatory compliance: ensure compliance with data privacy regulations such as GDPR, HIPAA, or regional laws by implementing features like data localization and secure storage options.
- Secure media sharing: encrypt all media files (e.g., images, videos) and transactions shared within the app to prevent unauthorized access or breaches during transmission.
- Screenshot protection: disable screenshots by default or notify users when screenshots are taken in sensitive conversations to prevent information leaks.
Advanced features
- Conversational messaging: incorporate interactive features such as structured conversation flows, images, carousels, and suggested replies. This can be achieved by integrating AI and technologies like Rich Communication Services (RCS).
- In-app messaging: leverage in-app messaging for personalized and timely interactions, capitalizing on high engagement rates.
Scalability and performance
- Server capacity: ensure servers are scalable to handle a growing user base efficiently. Plan for potential bottlenecks and optimize server configurations for peak load periods.
- Flawless updates: implement a system for seamless app updates without data loss, ensuring a continuous user experience.
How much does it cost and how long does it take to build a WhatsApp for Business alternative?
The cost and development time for building a WhatsApp Business alternative depend on several factors, including security requirements, features, infrastructure, and scalability.
