A Lamp Burning on Linden Street, Your Rough Diagram on the Desk, and the Engineer Who Will Test It Answering the Line.

Every Harbor Lantern engagement begins with a scoping call held by appointment. The engineer who will lead your test conducts it, reads whatever you send beforehand, and returns a fixed-fee proposal within two business days of hanging up.

The Directory

Four Lines Into the Practice, and What Each Is For

The practice keeps a short list of channels so that nothing is lost between them. Use the one suited to your purpose; each is read by the people who run the engagements.

  1. Telephone

    (718) 221-8018

    To arrange a scoping call, or — for clients already under engagement — to reach the designated test lead during an agreed testing window.

  2. Email

    info@theharborlantern.com

    For the particulars of your environment, procurement paperwork — W-9, vendor security questionnaires, MSA redlines — and links to prior reports shared through an encrypted service.

  3. Correspondence

    176 linden street, brooklyn, NY 11221

    For signed agreements and posted correspondence. Meetings at the practice are arranged in advance; the door is not staffed for callers without one.

  4. Hours

    By appointment — book a call

    Calls are scheduled around your engineering leads’ calendars, not ours. Propose a time in the form below and we will confirm it in writing.

What Follows Your Message

  1. A Reply From the Practice

    Written from info@theharborlantern.com, confirming a call time and naming the engineer who will take it.

  2. Confidentiality, If Required

    Should you want a mutual NDA in place before sharing architecture, send yours or request ours; it is countersigned before the call.

  3. The Scoping Call

    Forty minutes on scope, fragile systems, testing windows, and who answers if something breaks.

  4. A Fixed-Fee Proposal

    Delivered within two business days, with the fee stated once. It does not move after testing begins.

  5. Rules of Engagement

    Windows, source IPs, rate limits, and a stop word — countersigned before a single packet is sent.

Visiting the Practice

One Light on Linden Street, Kept On by Appointment

Most engagements are conducted remotely from first call to retest. Where a debrief is better held across a table — or a board wants to meet the people behind the report — we receive clients at the practice in Brooklyn.

Sensitive Material

How to Send Us the Things Attackers Would Like to Read

A security practice ought to be particular about its own inbox. These are the conventions we ask clients to observe from the first message onward.

Credentials

Keys and Passwords Stay Out of Email

Test accounts, API tokens, and VPN profiles are exchanged after the rules of engagement are signed, through the channel agreed for that engagement — never in an enquiry, never in a calendar invite.

Prior reports

Earlier Findings, Through an Encrypted Share

We read any previous penetration test report before quoting. Send it as a link from your own encrypted file service, or ask and we will issue a secure upload request addressed to you alone.

Authorization

No System Is Touched on the Strength of an Enquiry

We do not scan, probe, or test anything until written authorization is countersigned by a person with authority over the assets in scope. Sending us a domain is not permission to test it.

Paperwork

Questionnaires and Vendor Forms by Email

W-9 requests, vendor security questionnaires, insurance certificates, and MSA redlines may be sent to info@theharborlantern.com and are returned by the practice, not a reseller.

Before Your Next Questionnaire Arrives

The Line Is (718) 221-8018. The Engineer Who Answers Will Lead the Test.

Engagements from $2,350 for a retest to $39,800 for a full year of Harbor Watch, each fixed in writing after a forty-minute call.
