Case study · Family office

Phishing at the door, no perimeter behind it. So we went in first.

An offensive test showed a family office how far the phishing could reach. Then we set up its email security, put its domain and its reputation under watch, and left a GRC process running.

Details anonymized at the family's request.

The arc

Five chapters, from exposed to run.

Two chapters about what was open, three about what we set up and what keeps running. The steps climb as the office goes from being found to being watched.

Chapter 01 · What they were facing

The phishing was already arriving.

Phishing attempts were reaching the family office, and nothing stood at the perimeter to meet them.

A family office runs on trust between a small circle of people, and much of that trust travels by email. That is what made the phishing worth taking seriously: each message was a bet that someone close to the family would act on it.

  • PhishingPhishing attempts were arriving at the office.
  • PerimeterNo perimeter security was set up.
Chapter 02 · How we got in

So we tried the door ourselves.

TitanDef ran an authorized offensive test against the office, approaching it the way the people sending the phishing would. The test got in.

Getting in is the point of the exercise. It turns "we might be exposed" into a path the family can see, and into a list of exactly what has to close. The path started from the same kind of message that was already arriving.[CONFIRM]

Chapter 03 · What we fixed

Then we did the work ourselves.

We didn't hand over a report and leave. TitanDef did the work to set up the office's email security.

  • Sender authSender authentication on the office's domain (SPF, DKIM and DMARC).[CONFIRM]
  • PerimeterPerimeter security put in place where there was none.[CONFIRM]
Chapter 04 · What we watch now

Now someone is watching the edges.

With email security set up, the work turned outward: watching the places where trouble shows up before it reaches the inbox.

DOMAIN REPUTATIONDARK WEBREPUTATION
Domain

Domain reputation monitoring

How the office's domain is seen by the systems that decide whether its email is trusted.

Dark web

Dark web monitoring

Watching for the office's details turning up where stolen data is traded.

Reputation

Reputational monitoring

Watching for signals that put the office's reputation at risk.

Chapter 05 · The process

And a GRC process that keeps it that way.

The last piece is the one that lasts. An ongoing process now runs the office's governance, risk and compliance.

GOVERNANCERISKCOMPLIANCEONGOING

It is a process, not a project: it keeps running after the engagement ends, so security is something the office runs rather than something that happened once. The process runs on the TitanDef platform.[CONFIRM]

What changed for the family

From a door left open to an office that is run and watched.

The same office, before the engagement and now.

Before
  • Phishing attempts arriving
  • No perimeter security set up
  • An offensive test could get in
Now
  • Email security set up by TitanDef
  • Domain reputation and dark web monitoring
  • Reputational monitoring
  • An ongoing GRC process
