Enterprise Dataflow

We can help you design, develop, and launch your cloud-based platform. Our team has deployed enterprise applications on all the major cloud providers.

Kubernetes is a container technology that allows you to package up your application and move it effortlessly between on-premise infrastructure and cloud platforms. Kubernetes provides autoscaling, automated failover and recovery, availability, and transparency for your critical business services. Syscall 7 can help you port your existing applications to Kubernetes and guide you through the deployment of your production system.

Our team of enterprise web developers can help you build a slick user-interface for your custom application or help you architect a backend application that is scalable and load-balanced for enterprise deployment.

Software Analysis

Reverse Engineering

Software Reverse Engineering is sometimes the only method for addressing certain kinds of challenges. Here are some of the reasons why you might need to hire a competent firm to provide reverse engineering services for your business:

  • Interoperability – If your company is developing novel ways to interact with existing technology, then you might find yourself needing to identify the binary interfaces of closed-source, proprietary systems. For example, your product might want to speak a certain undocumented protocol in order to control a hardware device for which there is no published documentation.
  • Reclaim Ownership of Data – Sometimes closed-source technology holds a customer’s data hostage so a customer cannot switch providers. In this case, you might need to reverse engineer that particular product in order to regain ownership of your own data.
  • Combat Malware – If your company has been the victim of a cyber attack, understanding the internal workings of the malware with which you were attacked is vital to a successful mitigation campaign.
  • Recover Source Code – Sometimes companies lose their own source code and only have access to the binary executables. Reverse engineering technologies are so good these days that oftentimes we are able to reconstruct something very close to the original source code from just the raw binary executable.

Our team of reverse engineers are skilled in analyzing binary images targeting a wide range of computing platforms.

Performance Analysis

If your application performance is not optimal, your users will suffer and your competitors will seek to take advantage of that. Optimal performance means different things in different application contexts. Reliability is always an important factor, and so is responsiveness. We can generate metrics tailored to your specific application to help you find ways to improve the reliability and responsiveness of your software.
