Before installing a developer tool, verify who published it, where it came from, what it can access, and what code it may run. The right level of review depends on the tool’s reach: a small local utility and an extension with access to source code, shell commands, or CI credentials do not carry the same risk. These checks reduce risk; they cannot certify that software is safe.
1. Confirm the source, publisher, and exact tool
Start at the project’s official site or follow its link to an official package or extension registry. Check the publisher or namespace, the precise package or extension name, and whether the project links match. A familiar publisher name alone is not enough: a lookalike listing, misleading advertisement, or third-party mirror can point to a different file or maintainer.

OWASP recommends assessing both the supplier and the specific software offering, including its maturity and security history. See the OWASP Software Supply Chain Security Cheat Sheet and its CI/CD Security Cheat Sheet.
2. Check release integrity and provenance
When the publisher provides signed releases, follow its documented process to validate the signature. If it provides a checksum, compare the downloaded file against the checksum obtained through a trustworthy channel. A matching hash shows that the file matches that reference; it does not establish who created the file if the download and checksum came from the same compromised source.

- POWERFUL SECURITY KEY: The Security Key C NFC is the essential physical passkey for protecting your digital life from phishing attacks. It ensures only you can access your accounts.
- WORKS WITH 1000+ ACCOUNTS: Compatible with Google, Microsoft, and Apple. A single Security Key C NFC secures 100 of your favorite accounts, including email, password managers, and more.
- FAST & CONVENIENT LOGIN: Plug in your Security Key C NFC via USB-C and tap it, or tap it against your phone (NFC) to authenticate. No batteries, no internet connection, and no extra fees required.
- TRUSTED PASSKEY TECHNOLOGY: Uses the latest passkey standards (FIDO2/WebAuthn & FIDO U2F) but does not support One-Time Passwords. For complex needs, check out the YubiKey 5 Series.
- BUILT TO LAST: Made from tough, waterproof, and crush-resistant materials. Manufactured in Sweden and programmed in the USA with the highest security standards.
CISA’s developer guidance discusses integrity checking and binary composition analysis, while OWASP identifies signature validation as an important consumer-side check. Consult CISA’s recommended practices for developers.
3. Review permissions and credential access
Inspect the access requested by an IDE extension, CLI integration, package, or plugin. Depending on the tool, relevant access may include:
- Reading or changing files in a project or elsewhere on the device.
- Network access or permission to communicate with external services.
- Shell execution, tasks, or debugging capabilities.
- Repository access, OAuth scopes, or access to CI systems and credentials.
Ask whether each permission is necessary for the advertised function. For integrations and CI/CD extensions, grant only the minimum access required and vet the offering before connecting it to sensitive systems. OWASP’s CI/CD Security Cheat Sheet covers extension vetting and least privilege.

- POWERFUL SECURITY KEY: The YubiKey 5 NFC is the most versatile physical passkey, protecting your digital life from phishing attacks. It ensures only you can access your accounts
- WORKS WITH 1000+ ACCOUNTS: Compatible with popular accounts like Google, Microsoft, and Apple. A single YubiKey 5 NFC secures 100+ of your favorite accounts, including email, password managers, and more
- FAST & CONVENIENT LOGIN: Plug in your YubiKey 5 NFC via USB and tap it, or tap it against your phone (NFC), to authenticate. No batteries, no internet connection, and no extra fees required
- MOST SECURE PASSKEY: Supports FIDO2/WebAuthn, FIDO U2F, Yubico OTP, OATH-TOTP/HOTP, Smart card (PIV), and OpenPGP. That means it’s versatile, working almost anywhere you need it
- PRIMARY & SPARE KEYS: Just like having a spare house key, we recommend buying two YubiKeys - one for daily use and one as a spare. That way you’ll never get locked out of your accounts
4. Assess the maintainer and security response
Look for an identifiable maintainer or vendor, releases compatible with the tool’s current ecosystem, a clear way to report vulnerabilities, and evidence that security issues receive a response. These signals help assess whether the project is maintained and how it handles problems. A high download count by itself does not demonstrate safety.
OWASP includes maturity, maintenance, security history, and vulnerability response among the factors to consider when assessing suppliers and offerings. Its guidance is available in the Software Supply Chain Security Cheat Sheet and CI/CD Security Cheat Sheet.
5. Understand dependencies and installation behavior
For packages and tools that bring in other components, review the package metadata, dependency changes, and any lockfile updates. Pay attention to lifecycle scripts and post-install actions: installation can execute code on the local machine, not just copy files.
Rank #3
- Security Key : Protect your online accounts against unauthorized access by using FIDO2 and U2F authentication with T110. It's the world's most protective security key that works with windows, Mac OS, Linux as well as Chrome, Firefox, Edge and many other major browsers.
- Certified with the new FIDO2 standard, T110 provides the benefit of fast login and strong protection against phishing, account takeover as well as many other online attactks.
- Works with : Bank of America, Github, Google, Microsoft, DUO, Twitter, Facebook, Dropbox, Apple, ebay, BINANCE, mor and more.
- Fits USB-A port : Insert the T110 security key into the USB-A port of each service and log in conveniently with one touch
- For the driver download and user guide, please visit TrustKey Solutions Home support page.
- Use a lockfile and frozen install mode where the ecosystem supports them, so dependency resolution does not silently change.
- Restrict install scripts when practical, or allow only the scripts the project needs.
- Review dependency changes rather than treating a successful installation as proof that the contents are expected.
OWASP’s Developer Workstation and Dev Container Security Cheat Sheet discusses package installation exposure.
6. Keep unfamiliar workspaces restricted until reviewed
Do not trust a repository or workspace just because an editor asks whether to trust it. Opening an unfamiliar project may enable tasks, debuggers, or extension code. Keep the editor’s untrusted-workspace or restricted mode enabled while you inspect the project, and grant trust only when you understand what will be allowed to run.
OWASP’s workstation and dev-container guidance recommends keeping restricted mode enabled by default for untrusted repositories.

7. Scale the review to the tool’s blast radius
A tool that can read source code, reach signing keys or credentials, or change build infrastructure deserves stronger assurance than a narrowly scoped local utility. For a high-impact tool, consider requiring documented release integrity, component information, a security history, and organizational approval.
NIST’s IR 8397 describes software verification techniques including threat modeling, static analysis, secret detection, fuzzing, and addressing included packages and services. CISA’s developer recommendations also address software composition and integrity. These methods can inform a deeper organizational review; a personal checklist is not a substitute for a vendor’s full verification process.

No single check proves that a developer tool is safe. Assess the specific publisher, distribution source, release, permissions, dependencies, and intended use together. The more access a tool has to code, credentials, or build systems, the stronger the evidence and approval process should be.
