Get a comprehensive understanding of your security landscape. Companies large and start-up choose us for:
Exceptional code analysis and recommendations
We find the bugs other firms miss and make holistic recommendations to help you eliminate entire classes of them.
Formal verification of code correctness
We can confirm that your code behaves only as intended.
We’ve built the best available tools (many open-source) to dig deeper into your code than any other company.
You get best-effort support and guidance even after the audit ends, and you’ll receive the tools used in our assessments (plus updates).
Every assurance project includes:
Whether you need assurance for a complex platform or due diligence on a small codebase, contact us.
How can you ensure your software is free of backdoors, is secure, and meets regulatory standards?
Software is often built using third-party components and libraries for which the source code is unavailable
or is protected. If you can access the code, are you certain the binary was built from the same source?
Binary analysis is a necessary part of software security because it uncovers:
But, a deep investigation of binary software requires highly-specialized knowledge and tooling. Without the
right expertise, the process can be slow, difficult to scale, and requires monumental effort after each new
release or patch.
Our automated binary analysis:
Beyond automation, your Trail of Bits project team will explain any discovered issues and help you understand best practices for remediation. The result: fewer vulnerabilities and assurance that your software is as secure as it can be.
Blockchain is quickly becoming a more-secure way for organizations to transact. While decentralization and
continuous verification make Blockchain inherently more secure than other software, it is, at its core,
software attackers can exploit.
Applications built on Blockchain are susceptible to bugs, social engineering, malware, and more—all the same
exploit concerns as other software you build, buy, or deploy.
Our Blockchain security assessments help you understand:
Trail of Bits doesn’t just understand Blockchain security, we build industry-leading tools that find and
help fix vulnerabilities. We are the leaders in smart contract security assessments and the security
implications of the Solidity language, its compiler, and the Ethereum Virtual Machine.
Our tool offerings include:
Modern cryptography underpins all secure communication and collaboration. Correctly implemented,
cryptography maintains the confidentiality and integrity of data in even the most extreme circumstances.
However, this high level of assurance is fragile due to the mathematically complex nature of cryptographic
security. Not only do the underlying libraries need to be flawless, but an incorrect combination of
primitives or API calls can introduce subtle and dangerous vulnerabilities. Even well known protocols like
have been compromised
by incorrect use of cryptographic primitives.
Trail of Bits has extensive experience reviewing a variety of complex cryptographic libraries and protocols.
We also pride ourselves on keeping up with the latest research in cryptography and cryptanalysis. We know
where to look for bugs, and we know the classes of attack to protect against. Whether you’re building a key
management system or developing a protocol that achieves confidential transactions through zero-knowledge
proofs, we can certify your product has the protection guarantees you need. Count on us to:
Deliverables will be custom to your situation and may include:
Rapid development lifecycles and out-of-date tools and techniques can lead to vulnerabilities in software
that leave your organization open to exploits. Testing for logic flaws, memory errors, over-provisioned
access, and more is necessary to reduce your organization’s attack surface.
Trail of Bits’ Assurance team assesses your software using a multi-point evaluation framework. Testing
If your software passes, we will provide recommendations for continuous testing and improvement. If we find vulnerabilities, our Engineering team can work with you to bring your codebase up to the highest security standards and train your team on techniques and tools that Trail of Bits has built for continuous security improvement and attack surface reduction.
We help our clients identify and harden environment-critical infrastructures so they can deploy production systems with confidence. To do this, we audit cloud configurations and architectures against best security practices through manual and automated reviews of cloud services and Infrastructure as Code files such as Terraform, CloudFormation, and Azure Resource Manager files.
Organizations spend hundreds of work hours to build applications and services that will benefit customers
and employees alike. Whether the application/service is externally facing or for internal use only, it is
mandatory to identify and understand the scope of potential cyber risks and threats it poses to the
Can the software be reached from an external source? What is the likelihood that an attacker would want
access to it? If the software were exploited, what impact would that have on the organization from a
business, operational, and financial point of view?
These are just a few of the questions your company needs to ask as you’re building, deploying, and updating
applications and services.
But where and how do you start with an accurate threat model?
Trail of Bits has developed a comprehensive threat model that:
