Features and specs

What each product offers, as listed by its team.

Foam 6 features

SHIELD 3 features

Open Source
Foam is an open-source tool, which means it is free to use and allows for community-driven development and contributions. Users can modify the source code to fit their specific needs.
Markdown Support
Foam uses Markdown, a lightweight and easy-to-read syntax, making it simple to create and manage notes. This also allows for easy integration with other Markdown-based tools and platforms.
Integration with Visual Studio Code
Foam is designed to work seamlessly with Visual Studio Code (VS Code). This provides users with a powerful and familiar text editor environment, complete with extensions and customization options.
Graph View
Foam includes a graph visualization feature that helps users see and navigate the relationships between their notes, making it easier to understand and manage complex information.
Bidirectional Links
Foam supports bidirectional links, allowing users to create connections between notes in both directions. This enhances the note-taking experience by enabling a more interconnected and dynamic information structure.
Community and Documentation
Foam has a growing community of users and contributors, as well as comprehensive documentation. This support network helps users troubleshoot issues, share tips, and improve their knowledge of the tool.

Possible disadvantages

Limited to VS Code
Foam relies on Visual Studio Code as its primary environment. Users who prefer different text editors or platforms might find this limitation restrictive and less convenient.
Learning Curve
Although Foam leverages Markdown, users may still face a learning curve, especially if they are not familiar with VS Code or the specific features and extensions required to maximize Foam's capabilities.
Performance with Large Datasets
Foam can struggle with performance issues when handling large datasets or a high number of notes. This can lead to slow response times and inefficient workflows.
Limited Mobile Support
Foam is primarily designed for desktop use within VS Code, which means that mobile support is limited. Users looking for a seamless cross-platform experience might find this aspect lacking.
Customization Complexity
While Foam offers a high degree of customization, setting up and configuring the tool to meet personal preferences and workflows can be complex and time-consuming for some users.

Questions & Answers

What makes your product unique?

SHIELD's answer:

Most fraud solutions are web-first and rely heavily on personal data and static identifiers that are easily bypassed. They are also often focused on addressing fraud at specific checkpoints. SHIELD is device-first. Fraudsters can spoof data, accounts, and even identities, but they always need a device to act. This is why we stop fraud at the root.

Why should a person choose your product over its competitors?

SHIELD's answer:

Our plug-and-play SDKs and lightweight JavaScript snippets can be integrated in a matter of hours — not weeks or months. There’s no training period required, enabling your team to start detecting fraud immediately. Most customers see tangible results on day one, with zero disruption to existing workflows.

SHIELD's answer:

SHIELD works with digital businesses across every region and industry where trust and safety are mission-critical. Our customers include global unicorns and fast-scaling platforms in mobility, fintech, e-commerce, igaming, digital identity, and more.
