What’s Happening 24/7: A Tale of Securing a Point of Sale System with Toast

Securing the Point of Sale System

In the ever-evolving landscape of cybersecurity, businesses are constantly at risk of falling victim to unauthorized access, putting sensitive information and financial transactions in jeopardy.


One such incident unfolded when I was called to assist a client who had a Toast Point of Sale (POS) system compromised by an unknown individual. The breach not only made their network vulnerable to cyber-attacks but also jeopardized their Payment Card Industry Data Security Standard (PCI DSS) compliance, making it imperative to act swiftly and decisively.


The Breach:

The client approached me with a pressing issue: their Toast POS system had been compromised due to unauthorized devices being plugged into the network. This not only posed a significant threat to their data security but also raised concerns about the integrity of their PCI-compliant network, essential for processing secure credit card transactions.


Working with Toast:

One of the most reassuring aspects of this challenging situation was the client’s choice of Toast as their Merchant Service Provider. Toast proved to be a reliable ally in our mission to identify and mitigate the security risks. Their team of engineers collaborated seamlessly with our onsite BlissVector Tech experts to analyze the compromised network and devise a comprehensive plan to restore security.


The Process:

  1. Network Analysis:

Our first step involved a thorough analysis of the client’s network infrastructure. Toast engineers and BlissVector Tech experts worked hand in hand to identify vulnerabilities, trace the unauthorized devices, and understand the extent of the breach.

  1. Device Identification and Removal:

With a clear understanding of the compromised network, we swiftly identified and removed all unauthorized devices. This step was crucial to prevent further access and mitigate potential risks to sensitive information.

  1. Securing the handheld Wi-Fi for PCI compliance:

A secure Wi-Fi connection is paramount for maintaining PCI compliance. Toast engineers and BlissVector Tech collaborated to implement robust security measures, ensuring that the Wi-Fi network met the stringent standards required for processing credit card transactions securely.

  1. Collaborative Compliance:

Toast played a pivotal role in facilitating communication between our team and the necessary compliance authorities. With their support, we were able to expedite the process of getting the client’s network back into compliance with PCI DSS standards.



The incident of the compromised Toast POS system highlighted not only the vulnerabilities that businesses can face but also the importance of a collaborative approach to cybersecurity. The swift and effective partnership between Toast and BlissVector Tech showcased how a unified front can successfully identify, address, and remediate cybersecurity threats.

This experience serves as a testament to the crucial role played by Merchant Service Providers like Toast in ensuring the security and compliance of businesses relying on their services. In an era where cyber threats are omnipresent, a proactive and collaborative approach is the key to safeguarding the integrity of sensitive information and maintaining the trust of customers in the digital age.
