Best security tools

Security tools on this page are identity, secrets, endpoint, network, and application scanning products people actually bookmark. The list includes 1Password, Bitwarden, Okta, Auth0, CrowdStrike, Snyk, Tailscale, and consumer VPNs. It is not a full enterprise SOC catalog. Use it to pick controls you will operate, then hire a security review for the rest.

What are security tools on Bookmarkit?

Here, security tools are software that authenticates users, stores secrets, inspects endpoints, filters traffic, or finds vulnerabilities in code. Password managers and SSO are the usual first buys. VPNs and Zero Trust products change how people reach systems. Scanners such as Snyk sit in the repo. Chat apps such as Signal appear because people research private messaging next to security, not because a messenger is an SSO replacement.

This shortlist includes Auth0, Burp Suite, Clerk, Cloudflare WAF, Cloudflare Zero Trust, CrowdStrike, and 27 more.

Who this shortlist is for

  • Founders who still share passwords in a chat and need a manager plus SSO
  • Engineering leads adding Snyk or a TLS and WAF baseline
  • Individuals comparing VPNs and private messengers (with clear limits)

How we picked

We include identity, secrets, endpoint, VPN, and app-sec products with a catalog profile. We do not claim this is a complete compliance program.

  1. Primary job is authentication, secrets, threat detection, or private connectivity
  2. Public product page and a pricing or license signal
  3. Operable by a small team or an individual
  4. Messengers included only when privacy is the researched job

How to choose security software

Close the obvious holes first: passwords, SSO, and backups. Then add endpoint and repo scanning. A VPN does not replace those.

If this is the jobLook at
Secrets1Password, Bitwarden, or Proton Pass. Vault-class tools (HashiCorp Vault) when machines need secrets too.
Who can log inOkta, Auth0, or Clerk for app auth. Cloudflare Zero Trust or Tailscale for network access.
Code and dependenciesSnyk. Pair with review, not with a merge of every alert.
EndpointCrowdStrike or a lighter endpoint product if you have a security owner. Consumer AV is not a company program.

Frequently asked questions

What security tools should a startup buy first?

A password manager, SSO for the apps you already pay for, disk encryption you already have on the OS, and backups you have tested. Add Snyk or similar on the main repo. Add Tailscale or Zero Trust when you need private access. A VPN subscription is not the first control.

1Password vs Bitwarden: which should I use?

Both are password managers. 1Password is a polished commercial default. Bitwarden is a common pick when you want open source and a cheaper team plan. Compare sharing, SSO, and secret automation. Moving managers is painful. Pilot with a small vault first.

Does a VPN make me anonymous?

No. A VPN moves your traffic through another operator. It can help on untrusted networks. It does not hide you from the VPN provider, the sites you log into, or a broken client. Mullvad, Proton VPN, and others publish different trust models. Read them. Pair with a password manager and updates.

Is Signal a security tool?

Signal is a messenger with strong defaults for private chat. It is on this list because people research it next to security software. It does not replace SSO, endpoint coverage, or a password manager. For team chat you may still need Slack or a smaller tool with admin controls.

Where do agent security issues fit?

If you are connecting AI agents to tools and browsers, read our OWASP agentic rubric and the agentic-browser notes. Traditional security tools still apply (SSO, secrets, logging). Agents add prompt injection and over-scoping, which a VPN will not fix.
