“The second quarter of 2018 extends the continued strong growth for network security with consistent double-digit growth year over year across the top vendors. Firewall and UTM are the strongest areas of growth as network refreshes drive perimeter security refreshes and as vendors add new features and improve performance across all product lines,” said Robert Ayoub, program director, Security Products.
