In particular, the Ferox has spent several years as one of the most popular ships in very large nullsec fleets. It is cheap, durable, and its railguns can project damage to very long ranges. Its popularity has resulted in it receiving several nerfs over 2018 and 2019, but it is still a solid low-tech, even -usable, fleet ship. (It speaks volumes that two of its great competitors in this role, the Eagle and Muninn, are both Heavy Assault Cruisers and thus significantly more expensive and skill-intensive, and the Ferox still sees significant use.)
Outside of nullsec fleets, the Ferox also sees popularity in lowsec as a brawling-blaster platform, relying on its innately thick battlecruiser hull, six turret hardpoints, and often an XL Ancillary Shield Booster, to grind enemies apart faster than they can break through it.
