Six members of the environmental activist group broke onto the circuit during the opening lap of last year’s F1 race but a red flag owing to the crash for Alfa Romeo driver Zhou Guanyu meant the cars had slowed significantly when they passed the demonstrators on-track on the Wellington Straight.
Three of the protestors were given suspended prison sentences and the others handed community orders and unpaid work.
The Grand National at former F1 venue Aintree was delayed earlier this month by protestors said to be from the animal rights group Animal Rising, while Just Stop Oil interrupted the World Snooker Championships in Sheffield this week by climbing onto the table and dropping orange powder.
This has led to concerns that the London Marathon and The Open golf event later in the year might also be hit.
Silverstone managing director Stuart Pringle said events such as the 1987 track invasion to greet victor Nigel Mansell meant the venue was already advanced with its preventative measures.
Reflecting on the interruption in 2022, Pringle told Autosport: “Obviously there are lessons to be learned. Both our fencing and crowd stewards are significantly different to Australia [which was summoned by the FIA for a track invasion earlier this season]. We have been way more advanced.
“Frankly, since '87 and people hopping over the fence to embrace Nige, we've been pretty on that.
“We've done a massive internal review post-last year. We're working closely with the police again.”
