Chats are durable, so follow-up turns can resume with the same filesystem, checkout, agent session, system prompt, model, and MCP configuration even if the original sandbox is gone. Private GitHub, GitLab, and Bitbucket repositories are supported, and agents can read code, make changes, run tests, and iterate on failures just as they would locally. Every event is persisted, allowing interrupted streams to reconnect without losing the run.Starting Price: $0.00013 per GiB per hour -

FortiSandbox
Fortinet
Unlike previous generation of viruses that were non-sophisticated and low in volume, antivirus tools were sufficient to provide reasonable protection with their database of signatures. However, today’s modern malware entails new techniques such as use of exploits. Exploiting a vulnerability in a legitimate application can cause anomalous behavior and it’s this behavior that attackers take advantage of to compromise computer systems. The process of an attack by exploiting an unknown software vulnerability is what is known as a zero-day attack aka 0-day attack, and before sandboxing there was no effective means to stop it. A malware sandbox, within the computer security context, is a system that confines the actions of an application, such as opening a Word document, to an isolated environment. Within this safe environment the sandbox analyzes the dynamic behavior of an object and its various application interactions in a pseudo-user environment and uncovers any malicious intent. -

Bitdefender Sandbox Analyzer
Bitdefender
Sandbox Analyzer detects advanced zero-day threats prior to execution. Suspicious files are automatically uploaded to a secure on-prem or Bitdefender-hosted cloud sandbox for in-depth behavior analysis. Sandbox Analyzer, built by in-house machine learning and behavioral heuristic models, is a powerful forensic tool used in conjunction with Endpoint Detection and Response (EDR) to enhance an organization’s defenses against concealed sophisticated threats. It serves as a source of validation to provide enhanced visibility and focused investigation while optimizing effective threat containment. Suspicious files are analyzed in-depth by detonating payloads in Bitdefender's cloud platform, or in a secure customer virtual environment. Our sandbox technology observes malware behavior by simulating a ‘real target’ so that the malware will act as it would in the wild. Post analysis, appropriate actions are taken to effectively neutralize the threat. -

PDFik
PDFik
PDFik turns URLs or raw HTML into pixel-accurate PDFs through an asynchronous API: submit a job, get a job ID instantly, and receive an HMAC-signed webhook when the PDF is ready — or poll and download.
