Insider risk management: how to limit data loss caused by employees and contractors?
Most people who take data out of a company are not planning a theft: they send a file wherever it is easier to work on, or they get their password stolen. We show how to build an insider risk management programme that catches these cases early without turning the company into a surveillance system.
CVE-2026-93641: Stored XSS via Email in Zimbra Collaboration Suite
An unauthenticated sender can forge a share notification or calendar message that triggers stored XSS in Zimbra Classic or Modern, allowing the attacker to access mailbox data and act as the victim...
Network traffic analysis with NetFlow and IPFIX flows: what you see, what you miss and how it supports NIS2
The firewall guards the perimeter, EDR guards devices with an agent. Traffic between servers, printers and cameras inside the network falls outside both. We show what can be detected from flows alone, when you need packet capture and what network data you need within 24 hours of detecting an incident.

DORA and penetration testing: a testing programme in which TLPT is the summit, not the starting point
A firm asking "do we have to run TLPT?" is usually asking about the top of the pyramid before it has checked the base. DORA requires a testing programme from almost every financial entity, and TLPT only from those an authority designates. We separate the two levels and give the provision behind every claim.
How do you reduce mean time to detect (MTTD)? The four segments where the clock stands still
A company that 'shortened its MTTD' by buying a faster correlation engine usually shortened the shortest leg of the whole route. We break detection time into four parts, show the lever that belongs to each, and describe an honest measurement method — together with what this metric does not measure.
External infrastructure penetration testing: from inventory to retest
In most organisations the list of externally exposed assets is shorter in the spreadsheet than in reality. This text walks through the full cycle of external infrastructure penetration testing: surface inventory, scope and rules of engagement, the flow defined by NIST SP 800-115, how to read the report, and when to schedule the retest.
