At Nextdoorsec, we specialize in conducting comprehensive and professional penetration tests to help you proactively uncover your weakest links and identify the extent of damage an actual malicious attacker could cause your business.

And with our ability to provide testing remotely, you can rest assured that we’ll be able to meet your needs no matter where you’re located.

At Nextdoorsec, we understand that there are a variety of adversaries who could potentially attack your systems and cause damage. These may include malicious outsiders such as your competitors, hacktivists, nation-states, or organized cyber criminals.

Additionally, insiders such as your own employees or ex-employees, your customers (knowingly or unknowingly through their compromised IT systems), and your vendors or business partners (also knowingly or unknowingly through their compromised IT systems) could also pose a threat.
