Your organization needs a secure, reliable and scalable communications solution - one that’s easy to deploy and saves money. WhiteStar Chat is that solution, capable of bringing a unique feature set to your business to help reduce your exposure and reduce your cost. WhiteStar Chat uses the reliable WhiteStar hybrid peer-to-peer network to delivery speedy secure communications at a fraction of the cost of our competitors. WhiteStar Chat saves your business time and money, allowing your team to seamlessly communicate on their own smartphones, all without the liability of sensitive data leaks. --Data Protection - Compliant Networking WhiteStar Chat secures all your data with pure post-quantum cryptography (Category 5) by utilizing ML-KEM-1024 and ML-DSA-87 algorithms, alongside SHA-512 and AES-256. Not only does WhiteStar Chat reduce your liability, but it also is best for the welfare of your clients and all stakeholders. Standard SMS texting does not adequately protect customer data, and other chat applications do little if anything to prevent sensitive information that’s shared through them from leaving the application and being shared elsewhere. Everything sent over WhiteStar Chat is retained within the application, stored under military-grade encryption to help keep sensitive information safe. Plus, WhiteStar Chat never stores any information in a Cloud, which eliminates your exposure to potential data-breeches. --Save time, save money Organizations save time and money by using WhiteStar Chat. By having an open line of communication in their organization, WhiteStar Chat users minimize time spent on the phone, which allows them to focus more of their time on their clients, and less time spent on administrative tasks. By making communication more efficient, this saves businesses a lot of money - in fact, we estimate it saves around $6325 per year, per worker*. --Reduce risk and liability Complying with data handling standards can be a challenge, but WhiteStar makes it easy for your workforce to handle sensitive client data. WhiteStar Chat allows your team to send not only messages, but documents and files securely over the always-encrypted WhiteStar Network. There’s no chance of client data being accidentally left unencrypted, or misplaced on the wrong server. Making sure sensitive data is protected from unintentional leaks helps eliminate your liability and reduces your risk, saving you money and headache. --StarDrop - Drop Files Anywhere Sending fully secured files to your team and clients can be a serious headache. Luckily, WhiteStar Chat’s StarDrop file transfer system makes file sharing a breeze. StarDrop allows you to send encrypted files anywhere in the world between your devices without the need to store files in the Cloud. This means you can send important files to your team and clients without the worry of your files being leaked or compromised. Even better, StarDrop eliminates potential human error in the transfer of sensitive data - that way you can focus on what you do best, and let us be the cybersecurity experts in backing you up. --KeyP - Secure Keyboard Did you know that the keyboard you’re using to type on your mobile device, tablet or computer could be used to log the keys you press, potentially compromising sensitive data you’re typing on your device? Because of this potential threat, WhiteStar has built KeyP, a secure keyboard for WhiteStar apps. This helps us make sure that inputs into secure apps are truly secure, and that no information typed on KeyP is ever exposed to your phone’s operating system or other applications on your phone. KeyP never sends any information off your phone, nor does it log sensitive information like passwords or financial data. KeyP includes a word suggestion feature that is handled entirely locally on the phone, so your data is never processed by a third party.
