Security tools

Useful tools for safer digital operations.

Tools are useful when they answer practical questions: what is exposed, what changed, what can be restored, and which controls are missing. They do not replace hardening, monitoring, recovery planning, or professional assessment, but they are good places to start.

Breach and password hygiene

Start with credentials. Reused passwords and exposed accounts are still one of the fastest ways into a business.

Have I Been Pwned

Check whether email addresses or domains appear in known breach datasets.

Open
Free Business friendly

Does not fix reused passwords by itself; use it to trigger password resets and MFA review.

Bitwarden

Password manager for individuals and teams, with business vaults and self-hosting options.

Open
Open source Paid option

Still needs good onboarding, recovery planning, and access policies.

1Password

Polished password and access management for teams that want a managed product.

Open
Paid Business friendly

A password manager helps credentials, but it does not replace device, network, or backup controls.

KeePassXC

Local password database for users or teams that need an offline-first password store.

Open
Open source Offline

Database backups, sharing, and recovery become your responsibility.

Website and domain checks

These tools help expose weak HTTPS, missing security headers, and standards gaps in public-facing services.

SSL Labs Server Test

Review TLS certificates, protocol support, and HTTPS configuration quality.

Open
Free Web check

A strong TLS score does not mean the application itself is secure.

Security Headers

Check HTTP response headers such as CSP, HSTS, X-Frame-Options, and related browser protections.

Open
Free Web check

Headers reduce browser-side risk, but they do not fix vulnerable code.

MDN HTTP Observatory

Analyze public web security posture, with emphasis on HTTP headers and deployment hygiene.

Open
Free Web check

Use it as a signal, not as a complete security assessment.

Internet.nl

Check websites and mail domains for modern internet standards such as IPv6, DNSSEC, TLS, and mail security.

Open
Free Standards

Standards compliance helps resilience, but operational monitoring is still needed.

Suspicious files and URLs

Useful when you need a quick reputation signal before opening a suspicious link or file.

VirusTotal

Check suspicious URLs, domains, IPs, and files against many reputation and detection engines.

Open
Free Reputation

Do not upload confidential files, contracts, customer data, or private documents.

Email security

Email security is often where phishing, spoofing, and domain reputation problems become visible.

mail-tester

Send a test email and review deliverability, SPF, DKIM, DMARC, and spam-score signals.

Open
Free Email

A good score does not guarantee phishing resistance or mailbox security.

dmarcian DMARC Inspector

Inspect DMARC records and understand whether a domain is prepared to reject spoofed mail.

Open
Free Email

DMARC requires careful rollout so legitimate mail sources are not broken.

WordPress and exposed sites

Old plugins, abandoned themes, and unmanaged WordPress installs are common small-business exposure points.

Wordfence

WordPress firewall and scanner plugin for site owners who need practical visibility inside WordPress.

Open
Free option WordPress

It does not replace updates, backups, least-privilege admin access, or server hardening.

WPScan

WordPress vulnerability scanner for reviewing plugins, themes, users, and known exposure.

Open
Technical WordPress

Only scan sites you own or are explicitly authorized to test.

Network and remote access

Good networking is often the difference between a contained incident and a full business outage.

OPNsense

Firewall and routing platform for segmentation, VPN, filtering, traffic control, and network visibility.

Open
Open source Network edge

The platform is strong, but network design and rule discipline still matter.

WireGuard

Modern VPN technology for quiet, explicit, and secure remote access.

Open
Open source VPN

Keys, device ownership, routing, and access scope still need proper management.

Endpoint and file checks

Endpoint tooling is useful when it is enabled, maintained, and paired with sensible operational controls.

ClamAV

Open-source antivirus engine useful for mail gateways, file scanning, and Linux server workflows.

Open
Open source File scanning

Detection is only one layer; it does not replace patching, backups, or access control.

Microsoft Defender

Useful built-in Windows protection when it is enabled, updated, monitored, and configured properly.

Open
Windows Endpoint

Default endpoint protection is not a complete business security program by itself.

Backups and recovery

Backups matter only when they are encrypted, offsite, tested, and close enough to restore quickly.

restic

Efficient encrypted backups to local, self-hosted, or cloud storage backends.

Open
Open source Encrypted backups

You still need schedules, retention, repository checks, credentials, and restore tests.

Kopia

Encrypted, compressed, deduplicated backups with CLI and GUI options.

Open
Open source Encrypted backups

A backup tool is only useful when the restore process is known and practiced.

From checks to controls

Need help turning findings into safer systems?

A scan result is only useful when someone can interpret it, prioritize it, and turn it into a control that survives normal operations. Tell us what you found and what you need to protect.
