Featuring Glen Williams, Cyberfort CEO
The twist being that our rundown is based entirely on the views of 12 partner leaders
In a year in which cyber-attacks have begun piercing our daily lives, what have been the most potent and memorable incidents?
Who better to ask than a dozen leaders of MSSPs, consultancies and IT partners working on the front line of cybersecurity day in day out?
Whether it be the empty shelves and eyewatering losses at Marks & Spencer, or the tragic news last week of a patient death linked to an NHS attack, cybersecurity is now never far from the headlines.
At a government level, all eyes are now on cyber – cyber spending is a key component of new NATO plans to raise defence spending to 5% of GDP, while Australia this month introduced mandatory reporting of ransomware payments.
But what are the most signficant cyber-attacks of 2025 so far, and what implications does each have for how channel partners position their services?

Panel
Glen chose to speak about the Legal Aid Agency Attack
When: April
What happened?
The government initially became aware of a cyber-attack on the Legal Aid Agency’s online digital services on 23 April.
But on 16 May, it discovered the attack “was much more extensive than originally understood” and that the group behind it had accessed “a large amount of information relating to legal aid applicants”.
Three of our 12 panellists ranked this cyber-attack among the year’s most significant in the form of Chorus MD Nicola Saner, Cyberfort CEO Glen Williams and CyXcel Co-founder and COO Jano Bermudes.
“Investigations by the NCSC and NCA are ongoing, raising serious concerns about data privacy,” Williams said of his reasoning.
“Still early days for this one, but it’s eye catching due to the impact on the legal system in general, the scale of data stolen and the amount of time this may take to resolve,” Saner said when asked to justify her decision.
Channel takeaway
While investigations are ongoing, Saner claimed the cybersecurity industry can already glean some potential lessons from the cyber-attack.
“The implication for cybersecurity (again maybe not fully understood yet) seems to be a timely reminder about the risks of old and unpatched systems, a lesson well understood but again one which many organisations (especially in challenging financial times) struggle to deal with,” she said.
